fix: iPad tablet toolbar styling and PR #34 refinements

- Scope toolbar bottom-offset to phone breakpoint only (position:fixed);
  prevents double-correction on iPad where toolbar is position:relative
- Extract keyboard accessory bar styles to top-level mobile.css so
  /init, /clear, /compact buttons render correctly on iPad
- Use desktop-style toolbar sizing on tablet (430-768px): smaller font,
  no forced min-height, proper gap between buttons
- Show voice/mic button on tablet (was hidden at <1023px with no
  mobile replacement above 430px)
- Bump CSS cache-bust version to 0.1633
