carry the design language through gitea's remaining views

Commits, branches, cross-repo issues, notifications and organizations all move
onto DataRow, which is what makes them agree with each other — five lists that
were each hand-assembled from the same flex/gap/truncate parts now genuinely
share one row.

The repo header gets the same owner-muted / name-semibold split as the list row,
so the two screens agree about what a repository is called. Its description goes
from 12px to 14px, and the tab strip with it — those are read, not scanned, and
they were the smallest text on the busiest screen.

DataRow gains `href` for destinations outside the app. Notifications needed it:
Gitea's subject URL can usually be parsed back into an in-app route and
sometimes cannot, and the row should stay clickable either way rather than
becoming a dead div on the payloads that do not parse.

Empty states across the dashboard now say what the search actually covers.
"No open issues" was hiding that Gitea's cross-repo search only ever looks at
issues you created, are assigned, or are mentioned in — which is the difference
between a quiet week and a misconfigured token.

Typechecks clean and prettier is clean. Still not rendered in a browser.
