refactor(modules): simplify SVG asset handling across modules

Enhancements:
- Add optimized night‑variant detection for weather icons using a predefined list
- Replace `Svg` usage with direct `svg_file` calls throughout the todo widget, removing redundant relative‑path logic
- Update dock and battery modules to load assets via direct paths, eliminating unnecessary `get_relative_path` calls- Introduce `WEATHER_CACHE_TIMEOUT` constant and tidy up unused imports (`WEATHER_EMOJI_MAP` removed)
- Minor formatting and structural clean‑ups that improve code readability

Bug Fixes:
- Remove dead import of `WEATHER_EMOJI_MAP` and unused constant `WEATHER_EMOJI_MAP`
- Correct syntax of `condition_em` initialization to avoid potential rendering issues

New Features:
- None.
