feat: add restore-default button to SliderComponent

Adds an optional defaultValue prop to SliderComponent; when set, a
small reset icon (matching the existing "reset to default" pattern
used for advanced-toolbar icons) appears next to the value and resets
it back to that default on click. Wired up for the General tab's
"custom spacing" slider using DEFAULT_SETTINGS.spacing so it stays in
sync if the default ever changes. MacroBuilder's per-item Delay
slider is unaffected (no defaultValue passed, so no button shows -
there's no persistent default for a one-off macro action value).

Adds the new "Restore default" string to locale/en.json plus the ten
other filled locale files (untranslated, English placeholder) so the
locale completeness test suite still passes.
