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) Part of #254
