chore(browser): stabilize scrollbar + improve truncated text UX

- Set fixed row height (56dp) in card browser to prevent scrollbar jitter
- Add ellipsize/line limits and improved styling to browser columns
- Add ellipsize to note type field & tag list layouts
- Add long-press toast + tooltip to view full text for truncated items

Adds UX hints for truncated text and preserves smooth scrolling across lists.
