### What problem does this PR solve?
Issue Number: None
Related PR: None
Problem Summary:
`INSERT INTO ... SELECT ...` runs synchronously, but users need to observe
its load progress from another SQL session through `SHOW LOAD` by label. Before
this change, the running insert load job/progress information was not
registered early enough for `SHOW LOAD` to provide useful runtime visibility.
This PR registers a running `InsertLoadJob` after transaction creation and
sink finalization, initializes progress tracking after the job is registered,
marks the job as `LOADING` during execution, and reuses the same job/statistics
when the insert reaches `FINISHED` or `CANCELLED`. It also adds regression
coverage for observing S3/TVF-source `INSERT INTO SELECT` runtime progress,
including non-zero rows/bytes/file/backend details.
### Release note
Support observing INSERT INTO SELECT load progress through SHOW LOAD.
### Check List (For Author)
- Test <!-- At least one of them must be included. -->
- [x] Regression test
- `./run-regression-test.sh --run -d load_p0/insert -s
