pulsar-mouse: make the per-state widget colors configurable (#336)

* pulsar-mouse: make the per-state widget colors configurable

Both widgets hardcoded their state colors: error for a fault, secondary
while charging, error at the mouse's low-power threshold. The desktop
widget's one `color` setting only covered the normal state, and the bar
widget had no color setting at all.

Expose all four states (normal/charging/low/error) as `type = "color"`
settings on each widget, in the same shape battery-widget uses. Defaults
reproduce exactly what was hardcoded, so an existing install renders
identically until someone changes one.

The new settings are `advanced`; the desktop widget's pre-existing
`color` stays where it was so it does not disappear behind the toggle
for anyone already using it.

* pulsar-mouse: rename the bar's normal-state key to normal_color

A bar widget's plugin settings share one TOML table with Noctalia's own
per-widget presentation settings, where `color` already exists ("Color
role for this widget's icon and label"). A plugin declaring `color`
there does not shadow it, it aliases it - one `color = "primary"` under
[widget.<id>] drove both pickers at once, so setting either silently
moved the other.

Renamed to `normal_color`, which also makes the retest unambiguous: the
glyph follows the plugin setting while Presentation's own Color picker
stays on Default.

The desktop widget keeps plain `color` - no clash there, and renaming it
would break existing configs.
