feat: send screen recordings (#128)

* first pass implementation

* remove screenrecord shortcut hint

* refactor

* fix: prevent mirror review of screen recording

* feat: allow recording with webcam overlay

* fix: review screen recording without clipped content

* tidy keyboard hints consistent position

* refactor: re-use one component for screen picker

huddles and screen clips use same picker component now. We had to make
sure that tailwind works for both of them.

* fix: improve visibility of keyboard hints

During compose video or screen recording, the keyboard hints were
invisible if the content was super bright.
