…during EditLog replay (#62416)

### What problem does this PR solve?

Problem Summary:

Fix NPE in `StreamingInsertJob.replayOnCommitted()` during FE checkpoint
EditLog replay.

When a streaming insert task is canceled while its transaction is being
committed, `beforeCommitted()` silently returned without setting
`txnCommitAttachment`. The transaction still committed with a null
attachment written to EditLog. During checkpoint replay,
`replayOnCommitted()` calls
`Preconditions.checkNotNull(txnState.getTxnCommitAttachment())`,
throwing NPE.

Two issues fixed in `beforeCommitted()`:
1. Throw `TransactionException` when task is canceled instead of silent
`return`, preventing commit with null attachment. Consistent with
`RoutineLoadJob.executeBeforeCheck()` pattern.
2. Fix write lock leak — replaced broken `shouldReleaseLock` (always
`false`) with `passCheck` pattern: release lock on failure in `finally`,
keep it for `onStreamTaskSuccess/Fail()` to release on success.
