BLAT page polish from QA: Load example button, corrected input limits, wording fixes. refs #37996

Load example is a chip-style button with a mouseover instead of a hyperlink. Removed the
Show input limits modal; corrected the limits in hgTracksHelp.html, stale since 2013 (DNA is
75,000 bases per sequence and 187,500 combined, protein and translated 10,000 and 25,000),
added a #blatLimits anchor and pointed the two over-limit BLAT warnings and the form at it.
Genome selector: section title Target assembly, type-to-search hint in the dropdown,
Shortcuts: label, input and Query type select sized to match. Similar tools sidebar uses
house-style hyphens and corrects the findMotif name and description. Share and rename text
now states link lifetimes accurately (snapshot links last years, only sessions are
permanent). Alignment page buttons match .gbPill, summary strip spacing fixed, New BLAT
search button demoted from primary. Documents blatResultsGroup in ex.hg.conf.
