chore(settings): reset uiScale to 1.0 on startup while scaling is disabled

Users who had previously set a custom scale are silently reset to 100%
on next launch so they are not stuck at a broken zoom level. The stored
value is cleared in fontStore so the slider starts at 100% once the
feature is re-enabled.

Also credits nisrael for the ICY / AzuraCast PR #146.

TODO: remove the reset effect and re-enable the slider in Settings.tsx
when UI scaling is properly reworked.
