Fix: battery label positioning, custom keybinds not disappearing on hide_key_hints = false (#970)

## What are the changes about?

Fixes battery label positioning in regards to custom binds.
Since the label was on the top-left, it only accounted for the first line of built-in keybinds, and it didn't account for the other lines of custom ones.

This also fixes the custom keybinds not disappearing on `hide_key_hints = false`, which is my bad. whoops.

Also, with https://codeberg.org/fairyglade/ly/pulls/963 being a thing, we should probably think about deprecating this hardcoded battery label in favor of a custom label command, top-left by default.

## What existing issue does this resolve?

N/A

## Pre-requisites

- [x] I have tested & confirmed the changes work locally
- [x] I have run `zig fmt` throughout my changes
