v456

Code changes:

• Both exonNumber on and "mouseOver ${fieldName}" are now allowed in trackDb, this means that gene tracks now can have mouseovers (#324590). Max
• hgFind items now always pass the bigBed filters and always are in pack when we're doing squishyPack. This fixed a bug where squishyPack search results are not highlighted and stay squished (#32265). Brian
• Track short labels that are displayed on the main page now correctly encode special characters like < and > (#32512). Jonathan
• Stopped checking for data accessibility on the assumption that the trackDb build already did that. Add a little side-effect up higher in the call chain. This should probably be somewhere else, but in fear of breaking something new, I'm just popping it up one link in the call chain. Brian
• Added chainDupFilter which addresses a problem in axtChain where duplicated blocks are not chained. Brian
• A recent change to cropbox calculations caused GTEx Gene labels on expression plots to be omitted. The change has been reverted (#32445). Jonathan
• Continuous GenArk process improvements (#29545). Hiram

Data changes:
