Fix Turtle WoW compatibility: NPC spawning, quests, spells, realm display, and music

- Add TurtlePacketParsers with dedicated movement block parser (Classic format + transport timestamp)
- Fix quest giver status: read uint32 and translate vanilla enum values for Classic/Turtle
- Fix quest accept packet: remove trailing uint32 that vanilla servers reject
- Fix quest details parser: auto-detect vanilla vs WotLK format (informUnit field)
- Fix spellbook and action bar icons: fallback to WotLK DBC field indices when expansion layout fails
- Fix spell cast failure messages: translate vanilla SpellCastResult codes (+1 offset)
- Fix realm list: correct type values (6=RP, 8=RP-PvP) and population thresholds
- Fix music: disable looping for zone music, auto-advance to next random track when finished
- Add music anti-repeat: avoid playing the same track back-to-back
- Make TBC update block parsing resilient (keep parsed blocks on failure instead of aborting)
- Add right-click attack on hostile mobs
- Add name query diagnostic logging
