tooltips: Add hotkey hints and modify edit history tooltip.

This commit consists of the following visual changes:

- Add the hotkey hints in the tooltip of the view edit history option,
the shortcut (Shift + H) for which was added in PR #26245

- Swap "Click to view edit history." and the edit status string
(EDITED/MOVED/SAVING) to make the tooltip consistent with other
tooltips across the web app.

- Rename "Click to view edit history." to "View edit history", since
the "Click to view" part is evident from the icon as well as the the
keyboard shortcut hints.

Fixes #26581.
