LAV-3168: Match CREATE TASK serverless-property rejection errors (#3582)

* LAV-3168: reject invalid CREATE TASK serverless properties

Capture CREATE-specific Snowflake errors and verify each rejection leaves no
SQL-visible task. Validate trigger intervals, completion intervals, statement
sizes, and their size-order combinations before task insertion. Parse trigger
expressions so malformed values reach Snowflake-style property errors.

## Deviations
The ALTER error snapshots were advisory; CREATE-specific Cloud captures show
XXXLARGE is accepted, so it is covered by the existing valid-size CREATE test
rather than a new rejection case.

* LAV-3168: preserve 19-digit trigger values in task errors

Capture CREATE and ALTER Cloud errors for a 19-digit trigger interval.
Widen the numeric error format to cover the full signed 64-bit range.
The CREATE snapshot also confirms the rejected statement leaves no task.

Swept CREATE and ALTER minimum-trigger validation for undersized numeric
formats; fixed both call sites. Other task property validators are clean.
