Fix #161: Apply landscape keyboard height dynamically on orientation …

[FarzanArzoiy]

Description

This PR fixes Issue #161: the landscape height slider did nothing, while the portrait slider controlled both orientations.

Root cause: the keyboard height was calculated once on initial layout and never updated when:

• The user moved the landscape height slider.
• The device rotated between portrait and landscape.

Solution:

• Added refreshKeyboardHeight() method that recalculates the height using NeuralLayoutBridge (which already knows how to pick the correct preference based on orientation and foldable state) and applies it to the keyboard view.
• Called this method in onConfigurationChanged() so the height updates immediately when the device rotates.
• Called it in onSharedPreferenceChanged() when any height‑related preference (keyboard_height, keyboard_height_landscape, etc.) changes, so the landscape slider takes effect instantly.

Impact: users can now set independent heights for portrait and landscape, and both sliders work correctly. No other behaviour is altered.

Testing Performed

Manual Testing

Test Device:

• Device: Samsung Galaxy A31
• Android Version: 12
• CleverKeys Version: latest dev

Test Scenarios:

• Set portrait height = 40%, landscape = 60%, open keyboard in portrait → height is 40%.
• Rotate to landscape → height becomes 60%.
• Adjust landscape slider → height updates immediately.
• Rotate back to portrait → height returns to 40%.
• Ensure no other settings are affected (e.g., margins, opacity, layout).

Results:
All tests pass. The landscape slider now works exactly as expected, and orientation switching updates the height correctly.
