Portal and personal ticket requests now perform a single controlled
refresh + retry inside the production chain when the server rejects the
resolved access token with HTTP 401:
- Add optional ForceRefreshToken callback to PortalTicketConfig and
PersonalConfig. It receives the exact rejected token so the app-level
compare-and-refresh (ForceRefreshRejectedToken) can dedupe concurrent
rotations, and returns the fresh token.
- requestPortalTicket / fetchTicket retry the ticket request once with
the rotated token directly instead of surfacing an error and hoping an
outer loop retries; a second 401 stays fatal to prevent refresh loops.
- Refresh failures keep both the original 401 and the refresh error via
errors.Join; empty rotated tokens fail fast before hitting the server.
- Wire forceRefreshRejectedAccessToken into event consume (portal) and
personal stream sources; resolveSourceAccessToken strict semantics are
unchanged (provider errors still propagate, no static-token fallback).
- Tests: full DingtalkSource.Start -> startPortalTicket chain
(401 -> refresh -> ticket ok -> WebSocket event), rotated-token reuse,
refresh failure, nil-callback compatibility, second-401 fatality, and
app-level wiring.
