Fix storage display format and clean up warnings

Update storage display to match CLAUDE.md specification:
- Show drive temp/wear on main line: nvme0n1 T: 25°C W: 4%
- Display individual filesystems as sub-items: /: 55% 250.5GB/456.4GB
- Remove Total usage line in favor of filesystem breakdown

Clean up code warnings:
- Remove unused heartbeat methods and fields
- Remove unused backup widget fields and methods
- Add allow attributes for legacy methods
