refactor: extract language toggle into reusable components

Create Toggle and LanguageToggle components to reduce code duplication
and enable shared state across pages.

- Add Toggle.svelte: Generic iOS-style toggle with customizable accent color
- Add LanguageToggle.svelte: Language-specific toggle with localStorage persistence
- Refactor rosary page to use new toggle components
- Add language toggle to gebete page
- Toggle state persists across both pages via localStorage
- Reduce min-height of Ave Maria decades in monolingual mode (50vh → 30vh)
