Backend
- V18 migration adds AGENT_LIFECYCLE to condition_kind_enum. Java
ConditionKind enum shipped with this value but no Postgres migration
extended the type, so any AGENT_LIFECYCLE rule insert failed with
"invalid input value for enum condition_kind_enum".
- ALTER TYPE ... ADD VALUE lives alone in its migration per Postgres
constraint that the new value cannot be referenced in the same tx.
- V18MigrationIT asserts the enum now contains all 7 kinds.
Frontend
- Add describeApiError(e) helper to unwrap openapi-fetch error bodies
(Spring error JSON) into readable strings. String(e) on a plain
object rendered "[object Object]" in toasts — the actual failure
reason was hidden from the user.
- Replace String(e) in all 13 toast descriptions across the alerting
and outbound-connection mutation paths.
