- 19 tests covering:
- disableReasoning load from API (true, false, omitted, null)
- disableReasoning save to API (POST new + PUT update)
- databaseDialect save to API (populated, empty, PUT)
- datasourceSearch name lookup on job page load
(found by ID, found by string ID, not found, no ID, API error)
- uxState transitions: loading→configured, idle on job fetch
failure, idle on Promise.all entry failure
Also changed datasourceSearch lookup from fire-and-forget .then()
to awaited try/catch — guarantees name is populated before
uxState transitions to 'configured'.
