fix(i18n): Translate the remaining Git and pull request text (#116)

Multi-repo branch popup matches actions by their translated label (highlights and Chinese search now work) and translates its group headers. Conflict counts, relative times (shared dateFormat), in-progress operation titles, git operation progress/results, branch widget tooltips, diff/hunk counts, worktree markers, PR author line and review placeholders go through tx; the default "Changes" changelist shows its translated name. HexViewer read-only leaves the untranslated allowlist. 92 zh entries.
