perf: pre-generate Bible verse data and reduce DOM via conditional rendering

- Extract Bible lookup logic into shared src/lib/server/bible.ts module
- Add build script to pre-generate all 20 mystery verse lookups as static data,
  eliminating runtime API calls on rosary page load
- Update Prayer.svelte to pass showLatin/urlLang as snippet parameters; all 14
  prayer components now conditionally render only visible language elements
  instead of hiding via CSS
- Extract 4 inline mystery selector SVGs into MysteryIcon.svelte component
- Remove unused CSS selectors from angelus page
