chore: fix eslint errors

When the keyboard lock is supposed to be active (in full-screen mode), hitting the escape key (NOT long-pressing) should NOT dismiss the full-screen mode, and should send the Escape key through to the remote.

- Added awaits to the browser calls that need to complete in order.
- Cleaned up (mostly) duplicate code in the Absolute/Relative mouse handling
- Ensure we don't overrun any existing keyboard lock or pointer lock
- Release the keyboard lock when leaving full-screen
- Per standards, we need to acquire the keyboard and pointer locks before entering full-screen or the user may get multiple messages about exiting.
- Fixed all the missing/excess React dependencies.
- Moved the pointer lock bar up so it is visible.
- Somewhere along the way, the prompt to click the video when in relative-mouse-mode stopped being visible, restored it's visibility
- Fixed all the "should be readonly" warnings.
