feat(tvt): test-phase statue HP override, stationary guards, in-game rename

- Statue HP overridden to 100k at spawn (MaximumHealthOverride) for the test phase - no DB change.
- Guards made fully stationary by overriding their definition's IntelligenceTypeName to
  NullMonsterIntelligence at runtime (no wander, no chase); no DB change.
- Statue/guard in-game names rebranded to 'TvT Statue' / 'TvT Guard' (runtime designation override).
