feat(client): sprint 38 — free camera viewer, archetype strip, test fixes

- Add free camera mode (F4 toggle): WASD pan, scroll zoom, decoupled
  from player position (#898)
- Strip archetype-driven code: remove character_archetype, lattice_profile,
  and lattice color palettes from client (#882)
- Fix confrontation_monologue signal not firing in headless test mode (#867)
- Revive fog state behavioral tests: EXP_EXPLORED persistence, grow-only
  bounds, texture-resize copy, BoundaryWall handling (#879)
- Triage pre-existing test failures: fix examine_display dismiss timing,
  fog test position fragility, rendering snapshot assertions,
  time_display format (#871)
