feat: add the two-tier dashboard (task 0017)

Wire the bare `gitea-axi` home command to a two-tier repository
dashboard (ADR 0012): the short tier shows up to 3 open issues and 3
open PRs with the client-side `review` decision, and `--full` shows the
20-row open-PR table plus open issue counts grouped by label, aggregated
across every page of open issues up to the 1000-issue cap with a `+`
suffix when capped. Empty states render the raw `prs: 0 open` /
`issues: 0 open` strings; issue fetches pass `type=issues`; outside a
Gitea repo the dashboard errors with REPO_NOT_FOUND.

`paginate.ts` now reports whether pagination stopped at the cap, which
drives the label-count `+` suffix.
