docs: show the Python filtered refresh next to the SQL form (#4923)

Browse Source 
Adds Python where= examples next to the SQL ones.

Also fixes two examples that fail:
- Date filters now use date '2026-01-01'. A bare string fails on DATE
and TIMESTAMP columns (see [Dates, Timestamps,
Decimals](https://docs.lancedb.com/search/filtering#dates-timestamps-decimals)).
- The first example reads results with table.search().to_arrow(),
because table.to_arrow() raises on Enterprise.

where= needs lancedb 0.42.0 or later.
