Addresses two Major findings from PR review:
- Auth lockout no longer griefable: the throttle key is namespaced per path
and includes the client IP (web:<session>:<ip> vs desktop:<session>:<ip>),
so a flood of bad web-client auths can neither lock other clients of the
same session nor block the desktop from (re)authenticating. Per-socket
failure close and brute-force lockout are preserved.
- Relay web client XSS eliminated: app.html tab/macro rendering rebuilt with
createElement/textContent (no macro/tab value reaches innerHTML); inline
scripts/handlers externalized to /static/app.js and /static/login.js so the
helmet CSP now uses script-src 'self' (dropped 'unsafe-inline' for scripts).
