Fix talent system packet parsing and rank logic

- Parse SMSG_TALENTS_INFO with correct byte-for-byte structure:
  * Header: uint8 spec, uint8 unspent, be32 talentCount, be16 entryCount
  * Entries: entryCount × (le32 id + uint8 rank)
  * Glyphs: uint8 glyphSlots + glyphSlots × le16 glyphId
- Fix rank storage: store all talents from packet (rank 0 = first point)
- Fix UI rank logic: send rank 0 for new, rank+1 for upgrades
- Fix rank display: show (rank+1) for learned talents
- Add sanity checks: entryCount max 64, glyphSlots max 12
- Add network boundary logging for packet debugging
