raucao 7c4bad860a Store per-device user agent for remoteStorage authorizations
- Add user_agent to remote_storage_authorizations and rs_authorization_codes
- Capture the browser's user agent at consent, carry it on the authorization
  code, and store it on the authorization when the code is exchanged
- Store it directly for the implicit flow too

With the reuse shortcut gone, each authorization is already a distinct
per-device token; this adds the metadata needed to label and display them.

raucao cd2b4c9ba5 Address second-round review findings in the PKCE core
CI / Test (pull_request) Successful in 42s
- Enqueue the expiry job and the "app connected" notification on
  after_commit instead of after_create, so they only fire once the (now
  transactional) code exchange commits
- Enforce the PKCE code_challenge format (43-128 unreserved chars, S256)
  with model validations, not only at the controller
- Drop the now-unused RsAuthorizationCode#expired?
- Cover the client_id-vs-stored-client_id check

raucao 8dd0bf10ce Add PKCE support to remoteStorage OAuth
Implements the optional OAuth 2.0 Authorization Code grant with PKCE
(RFC 7636) for remoteStorage, as described in the remoteStorage spec
(section 10.1).

- Advertise the authorization and token endpoints plus the supported
  code_challenge method (S256) in WebFinger, and bump the advertised
  spec version to draft-dejong-remotestorage-27
- Add RsAuthorizationCode: a short-lived (5 min), single-use authorization
  code stored only as a SHA256 digest
- Add RsOauthManager services for issuing and exchanging codes, including
  S256 verification
- Add a cross-origin POST /rs/oauth/token endpoint that exchanges a code
  (and code_verifier) for an access token, with CORS and no CSRF token
- Consent dialog now carries response_type / code_challenge through the
  form and redirects with the code in the query string for the code flow
- Remove the existing-token reuse shortcut so every authorization results
  in a distinct authorization (and token)
