lancedb-gatefixer[bot] 9e73d440a3 test(python): cover schema-only vector table creation (#3882)
## Summary

- make the existing #1968 regression explicitly assert that schema-only
table creation succeeds
- verify the new table has zero rows and preserves the requested
fixed-size vector schema before accepting subsequent data

## Root cause

In v0.16.0, schema-only table creation sent an empty table through
vector sanitization, which calculated a remainder using `len(data)` and
raised `ZeroDivisionError`. Later refactors removed that runtime path,
but the issue-specific regression only asserted the final row count
after a subsequent add. This change makes the reported operation and its
expected empty-table state explicit so the original defect remains
directly covered.

## Validation

- `uv run --extra tests pytest
python/tests/test_table.py::test_create_table_without_data_with_vector_schema
-q`
- `uv --project python run --extra tests --extra dev ruff format --check
python/python/tests/test_table.py`
- `uv --project python run --extra tests --extra dev ruff check .`
- `git diff --check`

Fixes #1968
