security: add helmet, rate limiting, webhook auth, fix token storage, restrict hard deletes

- Add helmet for HTTP security headers (CSP, HSTS, X-Frame-Options, etc.)
- Add @nestjs/throttler for rate limiting (100 req/60s per IP)
- Add shared secret validation on Signal webhook endpoint
- Remove JWT token from localStorage, use Auth0 SDK memory cache
  with async getAccessTokenSilently() in API interceptor
- Restrict hard delete (?hard=true) to ADMINISTRATOR role in service layer
- Replace exposed Anthropic API key with placeholder in .env
