fix: custom conditions apply on add; correct server WS env docs

Custom conditions (per-campaign freeform) previously only persisted to the
campaign palette — Add button did NOT apply them to the targeted participant,
and badges rendered via CONDITIONS (missing custom ids) so applied custom
conditions did not display. Now:

- addCustomCondition(label, participantId) persists to palette AND toggles
  onto the participant in one step. Enter + Add button both pass p.id.
- Admin badge lookup uses allConditions (built-ins + custom), not CONDITIONS.

Shared contract: toggleCondition accepts ANY string. Prove it in tests:
- turn.combat.test.js adds CUSTOM_CONDITIONS ('hexed','rager',
  'marked_for_death','🛡️blessed') to the seeded queue + random pool, asserts
  condition-not-string invariant, and a dedicated add/remove round-trip test.
- replay-combat.js mirrors the same CUSTOM_CONDITIONS through the live backend.

Server-mode docs/env: REACT_APP_BACKEND_WS (stale pre-rename) -> correct
REACT_APP_BACKEND_REALTIME_URL=ws://.../ws in README, env.example,
docker/Dockerfile (STORAGE=ws -> server). DEVELOPMENT.md + scripts/README.md
now point to ./scripts/dev-start.sh as the primary dev entrypoint.

133 shared tests green.
