Fix licensing page ambiguities and LICENSE tag spelling, refs #37781

The license/index.html page had several passages easy to misread: a
claim that liftOver was the "only" data exception directly contradicted
by the clinical-genetics exceptions listed two paragraphs later, a
header/body tension in the graphics-reuse section, a garbled sentence
about entity type, a missing "than", and two same-named "Software:"
headings covering opposite licensing outcomes (free vs. commercial-restricted).

Also fixes the SPDX tag referenced on that page: the LICENSE files in
restricted directories used the misspelled "LicenceRef-proprietary"
rather than the standard "LicenseRef-proprietary", so grepping the tree
for the tag as documented turned up almost nothing.

Adds a link to the (currently sandboxed) list of tracks we cannot
distribute, next to the clinical-genetics exception examples.

 <h1>Website: No license or permission is needed to use the website, API and public MySQL server for academic, commercial or any other use</h1>
 <p>This is a public website. There is no license or permission needed to use
 the website and any services (API, etc) on it. You can also load your own data onto our
 website and look at it there, and use track hubs or custom tracks to configure
-how it is displayed, as a commercial, non-commercial or any other entity. However, 
+how it is displayed, regardless of whether you are a commercial, non-commercial or any other
+type of entity. However,
 when you use the UCSC Genome Browser in your work, please cite one of our
 <a href="../goldenPath/pubs.html">publications</a>.
 </p>

 <h1>Graphics: No permission is needed to reproduce a graphic produced by the Genome Browser</h1>
-<p>Permission is granted for reuse of all graphics produced
-by the UCSC Genome Browser website. There is no need to contact us to get permission. If your 
+<p>Blanket permission for reuse of all graphics produced
+by the UCSC Genome Browser website is hereby granted to everyone. There is no need to contact us to get permission. If your
 publisher, notably Elsevier, insists on getting approval, please direct them to this webpage.

 <h1>Data: No license is needed for the data files and database tables used by the Genome Browser</h1>
 <p>
 As far as the UCSC Genome Browser group is concerned, the raw table data and binary
 files used to create the graphics by the browser is freely available for both
 public and commercial use. This applies to data that is downloaded as files via 
 http, https, ftp or rsync, and equally when data is accessed through 
-the public MySQL server or via the web API. The only exception are the liftOver chain files,
-they can be linked, downloaded, used and redistributed, but only for non-commercial use
+the public MySQL server or via the web API. One exception is the liftOver chain files,
+which can be linked, downloaded, used and redistributed, but only for non-commercial use;
 see the <a href="http://hgdownload.gi.ucsc.edu/goldenpath/hg38/liftOver/">liftOver README</a>.
+A further set of exceptions, for certain clinical genetics tracks, is described below.
 
 </p>
 <p>Sometimes, the source databases or authors place restrictions on data. In very rare
 cases, the genomes come with citation requirements. The README.txt file in the
 download directory of each assembly shows the
 original restrictions pertaining to the genome
 sequence itself by the original authors; most assemblies do not have any restrictions.
 </p>
 <p>
 Certain genome annotation data, mostly on the human
 genome and in the domain of clinical genetics, have specific restrictions.
 For some of these, we are not allowed to make the data available. 
 Usually the data must be obtained from the source database directly in the
-original format or licensed, rather from UCSC. Examples are HGMD, LOVD, OMIM, Decipher,
-Genomenon, Genehancer and COSMIC. For viral genomes, any GISAID-sequences or any data
-derived from GISAID sequences cannot be shared by us. Please see the respective
+original format or licensed, rather than from UCSC. Examples are HGMD, LOVD, OMIM, Decipher,
+Genomenon, GeneHancer and COSMIC. For viral genomes, any GISAID-sequences or any data
+derived from GISAID sequences cannot be shared by us. See this <a href="/trackLists.html">list
+of tracks that we cannot distribute</a> for the exact set. Please see the respective
 track documentation pages on these assemblies for more details, by selecting
 the assembly and clicking the track title in the genome browser. They usually
 list or link to the exact license conditions. Files for these tracks are not
 available from our download servers, please contact us for questions or if you
 need a pointer to the respective conversion scripts in our Github code
 repository.</p><br>

 <p>
 The majority of the Genome Browser source code is available under the
 MIT license, see 
 <a href="https://github.com/ucscGenomeBrowser/kent/blob/master/LICENSE" 
 target=_blank>the LICENSE file in our source code repository</a>. As such, the 
 <a href="https://hgdownload.gi.ucsc.edu/downloads.html#utilities_downloads">
 Unix command line utilities</a> needed to build 
 tracks, track hub files, computational pipelines, and our
 hundreds of tools to filter, sort, rearrange, join, and process genome
 annotation files can be used and redistributed freely 
 via package managers and installation tools, even for commercial use (except BLAT/LiftOver).  
 Notable examples are bedToBigBed, wigToBigWig, overlapSelect, featureBits,
 pslMap, pslFilter and pslCDnaFilter.  </p>
 
 <p>
 The exceptions are source code directories with special LICENSE files in them. 
 These are <code>kent/src/blat</code>, <code>kent/src/isPcr</code>, <code>kent/src/jkOwnLib</code>, and 
 the programs that produce the graphical images or user interface
 for the UCSC Genome Browser. This includes the following subdirectories under 
 <code>kent/src/hg</code>:
 </p>
 
 <p><code>cgilib hgApi hgCollection hgFileSearch hgFileUi hgGateway hgGene 
 hgGenome hgIntegrator hgPal hgPcr hgPhyloPlace hgPublicSessions hgSession hgSuggest 
 hgTables hgTrackUi hgTracks hgVai hgc hubApi near visiGene liftOver</code>

 licenses and directories that they apply to: 
 <a href="https://github.com/ucscGenomeBrowser/kent/blob/master/LICENSE">
 https://github.com/ucscGenomeBrowser/kent/blob/master/LICENSE</a>.
 Directories under non-commercial licenses have LICENSE files in them that start
 with the "LicenseRef-proprietary" SPDX tag.  </p>
 
 <p>When you use the UCSC Genome Browser in your work, please cite one of 
 our <a href="../goldenPath/pubs.html">publications</a>.</p>

-<h1>Software: Download and installation of the graphical Genome Browser software 
+<h1>Graphical browser software: Download and installation of the graphical Genome Browser software
 and access to the source code is free for non-commercial uses but not commercial usage</h1>
 <p>Non-commercial usage for the Genome Browser graphical interface (primarily the "hgTracks" program),
 including download and local installation, aka setting up a 
 <a href="../goldenPath/help/mirror.html">"mirror"</a>, is free. When you use the UCSC
 Genome Browser in your work, please cite one of our <a
     href="../goldenPath/pubs.html">publications</a>.
 </p>
 
 <p>
 For commercial use, a license is required for download and local installation of
 certain Genome Browser webserver CGI binaries and source code. In the source
 code repository, the respective directories are marked by special LICENSE
 files in them. As specified above, this applies to <code>kent/src/blat</code>, 
 <code>kent/src/isPcr</code>, 
 <code>kent/src/jkOwnLib</code>, and the following subdirectories and 
 programs under <code>kent/src/hg</code>. The majority of license protected files 
 are the programs that produce the graphical images and the graphical user interface 
 for the UCSC Genome Browser:</p>
 <br>
 
 <p><code>cgilib hgApi hgCollection hgFileSearch hgFileUi hgGateway hgGene hgGenome 
 hgIntegrator hgPal hgPcr hgPhyloPlace hgPublicSessions hgSession hgSuggest hgTables hgTrackUi 
 hgTracks hgVai hgc hubApi near visiGene liftOver</code>
 </p>
 
 <p>
 Also, BLAT and isPCR, if needed, are covered by a separate license (see below). This concerns 
 the source code directories <code>kent/src/blat</code>, <code>kent/src/isPcr</code> 
 and <code>kent/src/jkOwnLib</code>.
