Raw filesystem paths were exposed in browser URLs, dev tools, and proxy logs.
Now all file-serving endpoints accept an opaque encrypted token (t= param)
derived from the session secret via HKDF, with a 4-hour TTL.
Backend:
- Add core/path_tokens.py with Fernet encrypt/decrypt (HKDF from .session_secret)
- Add file_token to all list/gallery/feed/search responses across 7 routers
- Accept optional t= param on all file-serving endpoints (backward compatible)
Frontend:
- Update 4 URL helpers in api.ts to prefer token when available
- Add 4 new helpers for paid-content/embedded-metadata URLs
- Update all 14 page/component files to pass file_token to URL builders
- Add file_token to all relevant TypeScript interfaces
