Richer note rows

Folder and inbox lists used to show just a note's title and a timestamp. Now each row carries its summary and tags too, so you can scan a folder and know what's inside without opening anything.

Titles have moved to a serif face, pinned notes get a star, and the date slips to the right in a lighter weight.

Notes without a summary still render cleanly: the row collapses to title and date, as before.
