Fix vanilla M2 animations, movement packets, and DBC locale

- Parse vanilla M2 animation tracks (flat arrays with M2Range indices)
  instead of skipping them, fixing T-pose on all vanilla models
- Use C4Quaternion (float[4]) for vanilla bone rotations instead of
  CompressedQuat (int16[4]) which produced garbage transforms
- Fix vanilla M2 attachment struct size (48 bytes, not 40) so weapons
  attach to correct bones instead of model origin
- Route movement packets through expansion-specific packet parsers
  instead of hardcoded WotLK format, fixing server-side position sync
- Fix Spell.dbc field indices for classic/turtle (Name=120, Rank=129,
  IconID=117) - were pointing to Portuguese locale column (+7 offset)
- Change guild roster keybind from J to O (WoW default)
- Add guild opcodes for all expansions
