Address CR feedback on insight + tp53 hub scripts. refs #37418

Drop duplicated bash() wrappers in favor of subprocess.run / check_output
with list args, eliminating shell=True, embedded-quote concerns, and
stderr-into-stdout merging. Centralize common operations as
run_sort_bed/run_liftOver in tp53FuncLib alongside existing run_bedToBigBed.

Switch HTML escaping to stdlib html.escape() consistently. insightHCIPriors
mouseover (previously unescaped) now escapes HGVS fields, addressing the
specific c.123A>G case Jonathan flagged. Replace invalid </br> tags with
<br> across all five affected mouseover sites.

 """
 TP53 VCEP Allele Frequencies (BA1/BS1/PM2) track generator.
 
 Pulls gnomAD v4.1 exome variants at the TP53 locus and classifies them
 per CSpec GN009 v2.4.0 thresholds:
 
     BA1            FAF >= 0.001                                     stand-alone B
     BS1            0.0003 <= FAF < 0.001                            -4 pts
     PM2_Supporting AF < 0.00003 global AND grpmax AF < 0.00004      +1 pt
 
 Uses faf95 (col 16) from the UCSC gnomAD v4.1 bigBed, plus grpmax AF
 (col 27) and global AF (col 15). CHIP note (col 29) surfaced in mouseover.
 
 Founder-effect ancestry groups (AJ/FIN/AMI/MID/Remaining) are EXCLUDED from
 the per-ancestry check per CSpec &#8212; our PM2_Supporting uses grpmax as a
 conservative proxy and flags when the proxy may miss qualifying variants.
