### Purpose
<!-- Linking this pull request to the issue -->
`LIMIT` pushdown previously always used the Fluss-only limit scan path. For
datalake-enabled FULL scans, this skipped the lake source, so union reads could
miss records that had already been tiered to the lake.
<!-- What is the purpose of the change -->
### Brief change log
<!-- Please describe the changes made in this pull request and explain how
they address the issue -->
- Avoid the Fluss-only limit scan path when a FULL scan needs to read from
the lake.
- Let the normal Flink source path perform lake + Fluss union reads in
that case.
- Add a Paimon IT covering `LIMIT` reads from an expired Fluss partition
whose data still exists in Paimon.
