Fix left/right arrow keys not working in dropdown search inputs (#19759)

Closes #12847 

Implements a two-mode focus management pattern for `SelectableList`
components with search inputs, resolving the conflict between text input
cursor movement and grid/list navigation.

### How it works

**Input mode** (search input focused):
- Left/right arrow keys move the text cursor normally
(`enableOnFormTags: false` on ArrowLeft/ArrowRight hotkeys)
- Up/down arrow keys blur the input and transfer focus to the grid,
entering grid mode

**Grid mode** (search input blurred):
- All arrow keys navigate the selectable list grid
- Pressing up arrow from the top row clears the grid selection and
refocuses the search input, returning to input mode
- Typing any printable character refocuses the search input (wildcard
hotkey with `enableOnFormTags: false`)
