style: apply ruff format across the repository

ruff format was never run repo-wide; CI now enforces 'ruff format --check', so normalize every module once. No behavior changes.

-  * N3  — ARC carries a `length` property; entity_select_smart length_range selects it
-  * N5  — properties parity: ezdxf sets bounding_box; MTEXT carries char_height + rotation
-  * NEW-dimauto-baseline-rotation — baseline dims run parallel to a rotated baseline
-  * NEW-dimauto-ordinate-misnomer — ordinate dims are staggered, not stacked at one offset
