* Update `_body.py`

* Remove unused function signatures.

* Update `_export.py`

* Update `_stub.py`

* Remove unused import modules.

* Update `_locations.py`

* Update `_modify_rows.py`

* Update `_tbl_data.py`

* Update `_utils_render_html.py`

* Update `gt.py`

* Update `_utils_render_latex.py`

* Update `_styles.py`

* Clarify that `sides` in `CellStyleBorders` does not support `ColumnExpr`.

* Update `_spanners.py`

* Update `_utils_nanoplots.py`

* Move `_flatten_list()` to `_utils.py`

* Update `_utils.py`

* Use `_flatten_list()` to deduplicate formatted cells in `_migrate_unformatted_to_output()`.

* Update `_formats.py`

* Update `_gt_data.py`

* Refactor `ColumnAlignment` to a `TypeAlias` as the `Enum` definition is unused in the code.
* Propose preserving the signatures of `__new__()` and `__init__()` in `Boxhead`.

* dev: switch to ruff

* dev: configure ruff for pyproject.toml and vscode

* chore: format with ruff, mostly removing newlines after block start

* dev: do not format ipynbs, format unused imports

* chore: run ruff formatter

* chore: run ruff formatter
