Delete caller-model routing + preflight admin UI

Backend (~273 lines):
- Removed GET/POST /api/caller-models endpoints (strategy/pool/map/fallback config)
- Removed POST /api/caller-models/{caller_key} override endpoint
- Removed GET /api/show/preflight diagnostics endpoint

Frontend:
- HTML: dropped Preflight header button, Caller Models settings panel,
  Preflight modal, and caller-model-badge/override from info panel.
- JS (~328 lines): removed loadCallerModels, saveCallerModels,
  updateCallerModelUI/Badges, overrideCallerModel, showCallerModelBadge,
  populateCallerModelOverride, runPreflight + render helpers,
  MODEL_ABBREVS, CALLER_STYLES, and all their listeners and init calls.
- CSS (~184 lines): removed .cm-*, .preflight-*, .caller-model-*,
  .model-tag, .info-badge.model, .caller-model-override rules.

Session fields (caller_model_strategy/pool/map/fallback/models,
caller_styles, caller_shapes) still present — they wire into shape
picking and checkpoint restore and get deleted in the next commits.
