Copilot review round 4.
- `getTokens(url, issuer)` falls back to the legacy unkeyed slot when that
issuer holds none — right for a connect, wrong for `collectGrants`, which
labelled the fallback with the issuer it happened to be iterating and paired
it with that issuer's credentials. During a partially migrated flow the clear
could have sent an old, unbound token to a newly discovered authorization
server. `OAuthStorage.getIssuerTokens` is the exact, no-fallback read; only
the ctx-less read still falls back, which is the one place it belongs.
- The TUI's warning tone was sticky. It lived in its own state while ~30 call
sites set ordinary OAuth notes without resetting it, so one revocation
failure left every later "Authorization updated" yellow, across server
switches. It is now DERIVED — `oauthMessageToneFor(message, warningText)` —
so it cannot outlive the message that earned it, with nothing to remember to
clear. Both setters stay plain `useState` setters: a `useCallback` wrapper
would be a value `react-hooks/exhaustive-deps` demands in seven dependency
arrays for an identity that never changes.
- Hook-level tests for the web wiring (previously missed): the per-server
opt-out and the backend-proxied fetch are now asserted to reach
`clearServerOAuthState`, so handing it the page-origin fetch — which a real
authorization server's missing CORS headers would reject — fails a test.
