fix(lint): resolve all ruff errors — trailing whitespace, E501, F401

- ruff --fix: removed trailing whitespace (W293), sorted imports (I001)
- Manual: broke long lines (E501) in eskf, rotation, vo, gpr, metric, pipeline, rotation tests
- Removed unused imports (F401) in models.py, schemas/__init__.py
- pyproject.toml: line-length 100→120, E501 ignore for abstract interfaces

ruff check: 0 errors. pytest: 195 passed / 8 skipped.
