// Route-wiring tests for the paste-credentials OAuth action.
//
// These exercise the rejection paths only — they all return 400 BEFORE the
// route touches finalizeTokens (Google APIs) or persistOAuthConnection (DB), so
// no network is hit. The happy path's finalize+persist is the same IO as the
// already-covered `device-complete` action; the new, security-relevant logic
// (allowlist + provider match + blob validation) is unit-tested in
// oauth-paste-credentials.test.ts and re-asserted through the HTTP boundary here.
//
// Auth is disabled via settings (requireLogin:false) so we reach the action
// dispatch rather than a 401. DB handles are released in test.after (CLAUDE.md
// learning: unreleased SQLite handles hang node:test).
