GreyGreed Inventory Toolkit 2.5.30

- Added an Expansion Labels Only bank-tab refresh watcher so changing Warband Bank tabs clears stale labels and redraws expansion-only labels.
- Wired modern bank refresh hooks and bank-tab clicks into the standalone Expansion Labels Only module.
- Kept the fix bank-only and avoided changes to normal inventory labels, AutoVend, Inventory Utility, Gear Marker, profession filters, or AutoLoot.
- Performed build cleanup validation for orphaned Lua files, obsolete files, TOC mismatches, and stale release artifacts.
