Fix counting and filtering on the dashboard page for issues (#26657)

This PR has multiple parts, and I didn't split them because
it's not easy to test them separately since they are all about the
dashboard page for issues.

1. Support counting issues via indexer to fix #26361
2. Fix repo selection so it also fixes #26653
3. Keep keywords in filter links.

The first two are regressions of #26012.

After:

https://github.com/go-gitea/gitea/assets/9418365/71dfea7e-d9e2-42b6-851a-cc081435c946

Thanks to @CaiCandong  for helping with some tests.
