feat: capture and display all item stat types in tooltips

Previously only the 5 primary stats (Str/Agi/Sta/Int/Spi) were stored,
discarding hit rating, crit, haste, attack power, spell power, resilience,
expertise, armor penetration, MP5, and many others.

Changes:
- Add ItemDef::ExtraStat and ItemQueryResponseData::ExtraStat arrays
- All three expansion parsers (WotLK/TBC/Classic) now capture non-primary
  stat type/value pairs into extraStats instead of silently dropping them
- All 5 rebuildOnlineInventory paths propagate extraStats to ItemDef
- Tooltip now renders each extra stat on its own line with a name lookup
  covering all common WotLK stat types (hit, crit, haste, AP, SP, etc.)
- Also fix Classic/TBC bag-content and bank-bag paths that were missing
  bindType, description propagation from previous commits
