feat: fixed audio, UI, and settings bugs; add hotkeys, footnote collapse, and enhancements

- Resolved uncaught‑promise error caused by faulty caching logic (Chrome extension).
- Documented Firefox cookie rejections (OptanonAlertBoxClosed, OptanonConsent) from biblegateway.com – harmless console noise.
- Clarified autoplay restrictions: audio now plays only after user interaction or when muted; narrator selection no longer triggers background playback while settings are open.
- Fixed dark‑mode toggle defaulting to “on” when settings aren’t saved (removed live preview).
- Moved narrator handling from main.js to settings.js to improve UX and transparency, especially on Firefox where autoplay is blocked.
- Increased vertical size of the Verse Analysis popup on desktop.
- Corrected mobile pop‑out buttons in Verse Analysis to work repeatedly (now use anchor links).
- Ensured Verse Analysis auto‑scrolls to the top when opened.
- Added hover‑text descriptions to the reference‑Bible dropdowns (source & translation).
- Added a link to the Westminster Confession of Faith in the “Important Literary Works” sidebar section.
- Implemented new hotkeys: Alt + E (export data), Alt + I (import data), Alt + M (export notes).
- Added autoplay‑next‑chapter audio logic with a toggle in Settings to disable it.
- Introduced a collapsible footnotes button inside the Verse Analysis popup, persisting its state.
- Updated Settings save flow to force a page reload after any change, eliminating issues such as audio restarting when the autoplay toggle is switched.
