The front page rendered every repository unsorted and unbounded — the same shape that made the timeline unusable, and it is at 23 now. Adds a name filter, sort by name, recent activity or size, and a limit, with Total alongside Count so a page can say '5 of 23'.

Sorting happens BEFORE the limit. The other order gives an arbitrary subset in the right sequence, which reads as correct and is not.

Activity comes from the event table's index — one walk stopping at the first row — so the column that makes a forge listing worth reading costs nothing.

Adds repo.get, so the settings page and the CLI stop scanning the whole listing to read one repository's settings. check-in: 4a3165db34 user: dmestas tags: trunk
