Add player death handling, race-aware faction hostility, and all-race texture support

- Death screen with "Release Spirit" button sends CMSG_REPOP_REQUEST
- Detect player death/resurrection via health updates (VALUES and CREATE)
- Faction hostility map now built per-character race instead of hardcoded Human
- CharSections.dbc texture lookup enabled for all races (was Human-only)
- Fallback texture paths use race folder names instead of hardcoded Human
- Player name in unit frame is clickable for self-targeting
