Fix Json Index bugs (#3398)

### What problem does this PR solve?

- JSON Index row_cnt_ 
One JSON row produces multiple index entries. row_cnt_ is not the same
as index entry count. Correct it.
- Planner cross-type matching
json_extract_double > N was treating > as >= for integer-typed values;
now preserves original compare type
- JSON flattener
:p: path-exists term emitted for objects and arrays (was only scalars),
fixing json_exists_path for non-scalar paths
- OPTIMIZE merge
removed broken reader_offsets_ adjustment that corrupted segment offsets
during chunk merge

Fix: Multiple Memory Indexers Cause BM25 Calculation Error (#3340)

Close #3339

### Summary

`ColumnIndexReader` may contain multiple memory indexers (one per
segment). However, `FullTextColumnLengthReader::GetDocTermCount()` was
only using a single `memory_indexer_` variable, causing `total_df_ <
doc_freq_` crash during BM25 calculation.

### Reproduction Steps

1. Set `optimize_interval` to 3600s
2. Run `TestMultipleIndexTypesImport` with snapshot restore enabled
3. The test will crash with `total_df_ < doc_freq_` error

### Expected behavior

_No response_

### Additional information

`UnrecoverableError(fmt::format("total_df_ {} is less than doc_freq_
{}", total_df_, doc_freq_));`

Fix PhysicalFilter::Execute (#3342)

### What problem does this PR solve?

When table is empty, prev_op_state->data_block_array_.empty() is true in
PhysicalFilter, we should return empty result instead of crash.
