Two related fixes after self-review of #2396:
1. workspace_bootstrap.go:62 — `SET status = 'failed'` was missed in the
initial sweep. Now parameterized as $3 with models.StatusFailed.
Test fixed with the additional WithArgs sentinel.
2. Drift gate now scans production .go AST for hard-coded
`UPDATE workspaces … SET status = '<literal>'` and fails with
file:line. This catches the kind of miss the first commit just
fixed — the original migration-vs-codebase axis only verified
AllWorkspaceStatuses ⊆ enum, not "no raw literals in writes."
Verified the gate fires: dropped a synthetic 'failed' literal into
internal/handlers/_drift_sanity.go and confirmed the gate flagged
"internal/handlers/_drift_sanity.go:6 → SET status = 'failed'".
