Add ADBC DB-API engine for SQL connections (#7664)

Closes #7549.

### What
- Adds `AdbcDBAPIEngine` (`marimo/_sql/engines/adbc.py`) to support
Arrow ADBC **DB-API wrapper** connections as first-class SQL engines.
- Uses `cursor.fetch_arrow_table()` for Arrow-native result fetching and
converts via existing `convert_to_output`.
- Implements catalog discovery via `adbc_get_objects()` /
`adbc_get_table_schema()` and respects `include_schemas` /
`include_tables` / `include_table_details` via `depth` + filters.
- Adds dialect inference from `adbc_get_info()` (cached), attempting to
derive dialect from vendor name.

### Tests
- `hatch run lint`
- `hatch run format --check`
- `hatch run typecheck:check`
- `hatch run typos -w`
- `hatch run +py=3.12 test:test tests/_sql/test_adbc.py`
- `hatch run +py=3.12 test-optional:test tests/_sql/test_adbc.py`

### Notes
- Integration tests for the SQLite ADBC driver are gated behind
`pytest.importorskip` and run in `test-optional` (adds
`adbc_driver_manager` + `adbc_driver_sqlite` there).
