lancedb-gatefixer[bot] 1c3cd1d918 fix(python): accept Arrow scalars in table updates (#3838) ...

## Summary
- convert PyArrow scalar values through their Python representation
before SQL literal rendering
- add an end-to-end regression for updating a fixed-size-list vector
from a queried FixedSizeListScalar

## Root cause
Python update literal conversion used single dispatch for native Python
and NumPy values but had no PyArrow Scalar registration. A
FixedSizeListScalar returned by a query therefore reached the
unsupported generic conversion instead of the existing recursive list
converter.

## Validation
- uv run --extra tests pytest python/tests/test_table.py::test_update
python/tests/test_table.py::test_update_with_arrow_scalar
python/tests/test_table.py::test_update_types -q
- uv run --extra tests pytest python/tests/test_util.py -q
- uv run --project python --extra tests --extra dev ruff format --check
python/python/lancedb/util.py python/python/tests/test_table.py
- uv run --project python --extra tests --extra dev ruff check .

Fixes #1228
