feat(sqlfile): add refresh, locate, and context menu to SQL Files panel (#2715)

* feat(sqlfile): add refresh, locate, and context menu to SQL Files panel

- Add per-folder Refresh and Reveal-in-file-manager buttons on each opened
  folder header, plus a Refresh-all button on the panel toolbar. Re-scan
  prunes expand state for paths that no longer exist after refresh.
- Add right-click context menus (via CustomContextMenu) for files, folders,
  folder headers, and the panel background: open, execute SQL file, reveal
  in file manager, copy path, expand/collapse all, refresh, remove folder.
- Highlight the selected tree row on click/right-click; clicking empty space
  clears the selection.
- Wire "Execute SQL file" from the panel into the App-level
  SqlFileExecutionDialog via connectionStore.sqlFileSource.filePath + a new
  prefillFilePath prop, so the dialog opens with the file preview preloaded.
- Add zh-CN/en strings under sqlFileTree.

* chore(i18n): autofill new translations

* fix(sqlfile): clear prefillFilePath on close, dedupe i18n keys
