fix(HoldingsDropdown): Add basic focus management and keyboard support

Closing #9967

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, activate focus in the amount input, then when Add button is enabled, pressing enter key should behave same than clicking on the button itself.
