mod: improve home screen with adaptive layouts, clock, and set time

- 1-book view: horizontal layout with cover left, title/author right
- 2-3 book view: fix cover stretching by preserving aspect ratio
- 0-book view: show "Choose something to read" placeholder
- Selection highlight now fully contains title and author text
- Add optional clock display in home screen header (AM/PM or 24H)
- Add "Home Screen Clock" setting under Display
- Add "Set Time" activity for manual clock setting via Settings
- Increase homeCoverTileHeight to 310 for title/author breathing room
