minor patch

- Added hotkey for manual inpaint: Shift +  R (Updated the hotkey list to display this)
- Moved Settings icon in the header to the end which is consistent with how most programs do it.
- Fixed some missing useEffect dependencies.
- Made the formatting of the Shorcut description text consistent.
- Removed the borders around the bottom toolkit buttons. The 1px border was choppy and the entire region was looking boxed and cluttered. Now I feel it looks cleaner and is consistent with the button in the header.
