refactor(ui): move Toggle component to Composition API + TS (#3281)

* refactor(frontend): move Toggle component to Composition API + TS

**Toggle.vue**:
- Enable composition API and TS
- Added `disabled` to props
- Remove redundant `checked`
- Replace `modelValue` and `emits` with `defineModel` compiler macro

**Others**:
- Replace emit handling and `model-value` with `v-model` where simple logic was used
  - Not `FeatureFlagSettings.vue` (contained custom code on receiving emit)
  - Not `Mods.vue` (contained custom code on receiving emit)
- Remove redundant `checked` attribute

* fix(app): toggles not updating value
