mteehan a365059976 security: harden JWT auth with session binding, CSP headers, and sessionStorage
- Reduce access_token_ttl from 900s to 300s (5 min) to shrink XSS exploit window
- Add session_id claim to JWT tokens tied to browser session (X-Session-Id header)
- Flask middleware validates session_id matches header on every request
- CSP headers: default-src/script-src 'self', no unsafe-inline/eval, frame-ancestors none
- X-Content-Type-Options: nosniff on all responses
- Move refresh token from localStorage to sessionStorage (tab-scoped, cleared on close)
- Timing-safe password verification (dummy Argon2id for unknown users)
- WebSocket auth also validates session_id header
- Add 5 session_id tests and 3 CSP header tests
