Found while verifying #21 against the live schema: the model writes
'completed_with_errors' (21 chars) when a bulk operation finishes with
per-ticket failures, but bulk_operations.status was varchar(20), so the
write failed with "Data too long for column 'status'".
This was latent — bulk status changes previously forced every transition
through, so failed was always 0. Now that they honour the Workflow
Designer, a partially-skipped batch is a normal outcome and hits it.
- migrations/001 widens the column to varchar(32) (idempotent).
- The baseline is updated to match, for fresh installs.
- The bookkeeping UPDATE is wrapped in a try/catch: it runs after the
ticket changes are committed, so an instance deployed ahead of its
migrations must not turn a completed operation into an error response.
Verified against the live database with a disposable-ticket harness:
comment-required rejection changes nothing, undefined transitions are
refused per ticket with a reason, allowed transitions still work, mixed
batches apply the valid half, and an already-Closed ticket is a no-op.
