fix(i18n): Translate the remaining UI text (Git, hierarchy, pull requests, dialogs, aria labels) (#114)

Hard-coded UI text, titles and aria-labels in about 110 components (Git panels, hierarchy, pull requests, dialogs, settings, welcome) now go through tx; spliced fragments became whole sentences (fileCount, noneFoundLabel, hierarchyTitle) and pull request states use keyed messages. 225 zh entries added, stale fragment entries removed.

Also: tx used as a tag without interpolations (tx`No checks`) now looks the text up exactly instead of as a template, so it is translated like tx("No checks"); the text-catalog test checks such tags as plain literals. Check and test counts reuse the existing "{count} passed" / "{failed} failing" entries.
