style: enforce consistent codestyle via ruff config and auto-fixes

- Configure ruff: isort, pyupgrade, bugbear, flake8 rules
- Auto-fix import sorting, redundant parens, exception chaining
- Remove from __future__ import annotations (Python 3.13+)
- Convert debug print() to logger calls
- Fix typo applicaiton → application in icon_resolver
- Remove bare returns in animator setters
- Move TYPE_CHECKING imports to runtime where used at runtime
