Ben 865cae4f61 feat(dashboard-auth): json-lines audit log at $HERMES_HOME/logs/dashboard-auth.log
Phase 1, Task 1.4. Records every auth event (login start/success/failure,
logout, refresh success/failure, revoke, session verify failure, WS
ticket mint) as one JSON object per line. Token-like kwargs (access_token,
refresh_token, code, code_verifier, state, ticket, cookie, Authorization)
are dropped before serialisation so the log never contains live secrets.

Write failures log at WARNING but never raise — auth flows must not fail
because the audit logger broke.

"""Audit log for dashboard-auth events.
Profile-aware location: ``$HERMES_HOME/logs/dashboard-auth.log``.
Format: one JSON object per line. Token-like kwargs are dropped before
serialisation so we never leak refresh tokens or JWTs to disk.
