### What problem does this PR solve?
Issue Number: N/A
Related PR: N/A
Problem Summary: Existing OLAP scan profiles only expose aggregate filter
counters, making it hard to understand the selectivity of each conjunct,
runtime filter, key range, and index-related filtering step. This PR adds
scan-local filter IDs and materializes detailed ScanFilterInfo and KeyRangeInfo
profile sections. Per-filter counters now show input rows, output rows,
filtered rows, stage participation, source expression or runtime filter debug
text, and runtime filter wait/always-true data where applicable. Empty runtime
filter fields are omitted for scans without runtime filters, and runtime filter
IDs remain distinct from scan filter IDs.
### Release note
Add detailed OLAP scan filter profile counters in query profile.
### Check List (For Author)
- Test: Manual test
- ./build.sh --be
- Ran local profile_level=2 scan and runtime-filter join queries on
scan_filter_profile_db and checked generated profiles
- Behavior changed: Yes. Query profile includes detailed OLAP ScanFilterInfo
and KeyRangeInfo counters.
- Does this need documentation: No
