Molecule AI Backend Engineer b6d9af5fc2 feat(platform): Temporal checkpoint DB persistence layer (#788)
Adds step-level checkpoint storage so workflows can resume from the
last completed step after a crash or restart without replaying prior work.

- Migration: `workflow_checkpoints` table — workspace_id (FK + CASCADE),
  workflow_id, step_name, step_index, completed_at, payload JSONB.
  UNIQUE(workspace_id, workflow_id, step_name) + covering index on
  (workspace_id, workflow_id, completed_at DESC).

- Handlers (platform/internal/handlers/checkpoints.go):
  POST   /workspaces/:id/checkpoints        — upsert via ON CONFLICT DO UPDATE
  GET    /workspaces/:id/checkpoints/:wfid  — list steps ordered step_index DESC
  DELETE /workspaces/:id/checkpoints/:wfid  — clear on clean shutdown (404 if none)

- Router: all three routes on the wsAuth group (WorkspaceAuth middleware);
  workspace A's token cannot reach workspace B's checkpoints.

- Tests (11 cases, sqlmock + race-safe): upsert-insert, upsert-update,
  payload forwarding, list-ordered, list-not-found, rows.Err() → 500,
  delete-success, delete-not-found, callerMismatch 403 on all 3 endpoints.

Closes #788. Parent: #583-1.
