A login → decrypt → edit → re-encrypt page so account settings (the
addon URLs + TMDB key) can be changed from any browser instead of typing
them on a TV. Doubles as the per-user config-update tool (editing a live
account's config, which the one-time onboarding template can't do).
- pb_public/settings.html: auth-with-password, load the owner's
addon_config (rules already scope to profile.user), decrypt the blob
in-browser with the password (PBKDF2→AES-GCM, byte-identical to the app
+ onboarding page), edit fields, re-encrypt and PATCH.
- Crucial: re-encrypt reusing the record's EXISTING salt, so the derived
key is unchanged and an already-logged-in device (which cached that key
and has no password on a restored session) decrypts the edited blob
with no re-entry. A fresh salt would force a TV re-entry — the opposite
of the point.
- 18+ fields (adult addon URL + enable toggle) render only for an account
with nsfwEnabled; a clean account never sees them and their stored
values are carried through untouched on save.
- pb_hooks/settings.pb.js: /settings → /settings.html redirect.
No server logic beyond the redirect — all crypto/IO is client-side against
the existing collection API. Crypto round-trip + salt-reuse + wrong-key
rejection verified against the app's format (WebCrypto, Node).
