orgtoken.Validate() runs a synchronous UPDATE org_api_tokens SET
last_used_at after every successful auth scan. Tests were missing the
sqlmock ExpectExec for this call — the code discards the error
(_, _ = ExecContext) so CI passed, but ExpectationsWereMet() could
not detect a regression where the UPDATE was accidentally removed.
Adds strict mock expectations for all four WorkspaceAuth+org-token
test cases: SetsOrgIDContext, OrgIDNULL_DoesNotSetContext,
DBRowScanError_DoesNotPanic, and SetsAllContextKeys.
Fixes: GH#1774
