[Community Permissions]: Keyboard support and focus management

[micieslak]

Description

Currently it's impossible to navigate in community permissions UI using keyboard. Also accepting popups using Enter or rejecting using ESC is currently not covered. When popups are opened, focus should be set to proper components (like search text field). In some cases navigation using Tab/Shift+Tab could be useful.

Notes:

1. Focus/keyboard related behavior should be discussed with the design team.
2. This task after some additional analysis probably could be split into smaller tickets.

Since this is a big task / topic and also needs analysis what we can try to have for milestone 11 are these subtasks:

• [ ] When Holdings dropdown is open, activate focus to searcher in assets and collectibles. Changes focus to ENS input in case ENS tab is active.
• [ ] In Holdings dropdown, when ENS tab is active and Add button is enabled, pressing enter key should behave same than clicking on the button itself.
• [ ] In Holdings dropdown, when one asset or collectible has been selected, and the popup is on the following view, activate focus in the amount input, then when Add button is enabled, pressing enter key should behave same than clicking on the button itself:

move preferably after MVP as specs are still missing and overall it needs a lot of rework&planning

[iurimatias]

moving this, because this is not currently high priority for MVP and most of all needs to be part of the keyboard specs
