feat(modules): restructure battery UI and add dynamic layout rebuilding

New Features
- Introduce `get_battery_icon_file` to generate battery icons based on percentage and charging state.
- Add fallback Bluetooth control using `rfkill` when Fabric Bluetooth fails.

Enhancements
- Refactor layout management with `_rebuild_layout_from_config` and dynamic indicator instantiation.
- Replace large `EnergyModeButton` class with lightweight utility functions.
- Simplify notification icon updates using `dynamic_file`.

Bug Fixes
- No explicit bug fixes; changes focus on feature additions and refactoring.
