Disable battery status display by default (#852)

A couple things to fix in the new battery status display configuration.

I think this should be disabled by default. My reasoning:
- Historically a conservative approach is taken with new capabilities in Ly; even the clock is disabled by default
- The existing default creates a regression (error message) for anyone without `/sys/class/power_supply/BAT0` on their system (all non-portable PCs, and laptops that use a different identifier)
- The battery status check causes animations to momentarily hang at a regular interval

Other changes:
- Comment for `battery_id` aligned with similar config switch comments (description / useful information / effect of null setting)
- `battery_id` moved to its correct alphabetical position in the config file
- Setting aligned between `Config.zig` and `config.ini` (the prototypical config file should reflect the actual default)
- Configurations prefixed with `hide_` alphabetized
