Add random verse feature with keyboard shortcut

New random verse functionality:
- /random-verse route randomly selects a Bible verse
- Picks random book, chapter, and verse
- Redirects to the selected verse page
- Enables serendipitous Scripture discovery

Navigation integration:
- Added "Random Verse" link to sidebar navigation
- Placed between "Verse of the Day" and "Reading Plans"

Keyboard shortcut:
- Press 'r' anywhere on site to jump to random verse
- Added to keyboard shortcuts help (press '?')

This feature encourages exploration and discovery of
less-familiar Scripture passages. Each visit provides
a new, randomly selected verse from anywhere in the
66 books of the Bible.
