fix(table-core): preserve columnFiltersMeta in filterRowModelFromLeafs

[ErfanBagheri404]

Fixes #6074

When filterFromLeafRows is true, filterRowModelFromLeafs recreates each row via constructRow and copies columnFilters, but neglects to copy columnFiltersMeta. Users who store filter-rank metadata (e.g. for fuzzy-sort use cases) find their data wiped on every filter recalculation.

Copy columnFiltersMeta alongside columnFilters when building the filtered row model from leaf rows.

Leaf-first filtering now copies columnFiltersMeta when it reconstructs rows. This preserves filter metadata during recursive filtering.

I pulled the current filterRowsUtils.ts and confirmed the gap directly: filterRowModelFromRoot and filterRowModelFromLeafs both reconstruct rows via constructRow, but only the leaf-up path drops columnFiltersMeta on the copy while keeping columnFilters. Anything that reads per-row filter match metadata (e.g. highlighting the matched substring for a fuzzy filter) would silently lose it whenever filterFromLeafRows is enabled, with no equivalent loss in the root-down path. The fix is a one-line, symmetric addition that matches how columnFilters is already handled two lines above, so it's low risk.
