CSS: extract notification panel inline styles to classes

- lt-notif-empty: replaces all hardcoded padding/font/color/align on
  the empty-state and loading/error text in the notification bell panel
- lt-notif-view-all: replaces width/text-align/display/font-size inline
  style on the 'View dashboard' footer link
- lt-notif-dot: moves border-radius:50%;margin-top from inline style
  (only background color remains inline, which is dynamic per-severity)
- Initial 'Loading…' text in the panel HTML uses lt-notif-empty
