Add setting for the keyboard to auto-open when reaching top of app drawer

[Rage0fKratos]

Description:
When scrolling back to the top of the app drawer, the search field is visible and may already be focused, but the keyboard does not automatically open. The user must tap the search bar to trigger the keyboard.

Steps to Reproduce:

1. Open the launcher
2. Go to app drawer (or screen with search bar)
3. Scroll down the list
4. Scroll back up to the very top

Expected Behavior:
If the search field is focused (or becomes active at top), the keyboard should automatically open without requiring an additional tap.

Actual Behavior:
Keyboard does not open automatically. Manual tap on the search bar is required.

Device Info:

• Device: Samsung S23
• Android Version: 16
• Launcher Version: 1.5.1

@luantak let me know if it's expected behaviour. If not, i can pick it.
we can add a setting to enable or disable this behaviour.

This is expected, the behavior you want seems confusing to the vast majority of users. If you want to add a setting for this yourself a pr is welcome.
