fix(app): browser pane keyboard tweaks

- Refresh icon: use single-arrow RotateCw instead of two-arrow RefreshCw
- URL bar selects all text on focus
- Cmd+R now reloads the active browser pane (tracked via IPC) when
  the URL bar has focus, instead of reloading the Electron window
- Forward Paseo shortcut keys (b, e, w, t, k, /, \, comma, digits,
  enter, arrows) from the embedded webview to the main window so
  sidebar/tab/etc. shortcuts still fire when focus is inside the
  loaded page
