The lazy on-fetch OAuth token refresh persisted the new access token with a raw
`UPDATE variable SET value = <db-encrypted>`, bypassing the secret-backend
abstraction. With an external secret backend (AWS Secrets Manager / Azure Key
Vault / Vault), secret reads resolve through the backend and ignore
`variable.value` entirely, so refresh advanced `account.expires_at` and updated
Postgres but never wrote the new token to the external store. Every read that
did not itself trigger a mint kept serving the frozen connect-time token, which
expired ~1h after connect (RefreshError on Google clients).
`windmill-oauth` can't depend on `windmill-store` (circular), so variable
persistence moves out of `refresh_token{,_for_account}` (which now only exchange
the token + update the `account` row and return the new token) into the
`windmill-store` callers, via a new `store_oauth_token_value` helper that writes
through the configured backend and stores the returned value (encrypted blob for
the DB backend, `$...:` marker for external backends) in `variable.value`.
If persisting the refreshed token fails (more likely now that it can be a
network write to an external backend) after the account was committed fresh,
`store_oauth_token_value` resets `expires_at` to the past and records
`refresh_error` — looking the account up via `variable.account` — so the next
fetch retries instead of serving the stale token for the whole token lifetime.
Also add `windmill-store/tests/oauth_refresh_secret_backend.rs`, an opt-in e2e
regression suite (RUN_SECRET_BACKEND_E2E / RUN_AWS_SM_TESTS) covering database
and external (AWS SM via LocalStack) backends plus the self-healing reset.
Verified against Postgres + LocalStack: 3 passed.
EE companion (oauth_refresh_ee.rs: 3 refresh paths) merged via #607; this OSS
half completes the fix (ee-repo-ref already at EE main 481ea7f).
