Fix broken external links in trackDb HTML docs found by uiLinks cron (2026-03-23 run).

Updated 261 trackDb HTML and .ra files:
- Fixed 404s: replaced dead URLs (sequenceontology.org wiki, compgen.cshl.edu PDFs,
chori.org, PolyPhen v1, uswest.ensembl.org, RIKEN GSC) with current locations;
removed links for defunct sites (snpdata.cshl.edu, zfrhmaps, renlab encode3 download,
oia.gachon.ac.kr, phylohmm.pdf across 92 conservation track docs).
- Fixed 301s: updated http→https (encodeproject.org, flybase.org, gene-regulation.com,
drive5.com/muscle, microbesonline.org/fasttree, brain-map.org); updated moved domains
(blackwell-synergy→wiley, genome.cshlp.org path fix, sanger.ac.uk path fix);
removed hijacked domains (seqll.com, orfeomecollaboration.org, farnhamlab.com).
- Fixed 302s: updated http→https (ensembl.org, affymetrix.com, asntech.org,
cdna.eva.mpg.de, arcseqhub.com); updated moved domains (dfam.janelia.org→dfam.org,
hmmer.janelia.org→hmmer.org, immuneepitope.org→iedb.org, ensembl variation path).

No RM.
