Replace hotkey scopes by focus stack (Part 4 - Inputs) (#12933)

# Replace hotkey scopes by focus stack (Part 4 - Inputs)

This PR is the 4th part of a refactoring aiming to deprecate the hotkey
scopes api in favor of the new focus stack api which is more robust.
Part 1: https://github.com/twentyhq/twenty/pull/12673
Part 2: https://github.com/twentyhq/twenty/pull/12798
Part 3: https://github.com/twentyhq/twenty/pull/12910

In this part, I refactored all inputs in the app so that each input has
a unique id which can be used to track the focused element.
