fix: talent screen hang (uint8_t overflow) and camera pitch limit

- Change maxRow/maxCol from uint8_t to int in renderTalentTree to prevent
  infinite loop: uint8_t col <= 255 never exits since col wraps 255→0.
  Add sanity cap of 15 rows/cols to guard against corrupt DBC data.
- Fix dangling reference warning in getFormattedTitle (lambda reference)
- Raise MAX_PITCH from 35° to 88° to match WoW standard upward look range
