[Android] Fixed the SoftInputMode issues with modal pages

[Ahamed-Ali]

Root Cause of the issue

In the OnCreateDialog method, CustomComponentDialog is used to create the dialog, and its SoftInputMode defaults to AdjustUnspecified. As a result, the behavior varies based on the layout:

• If a ScrollView is present, the window appears to resize.

• Otherwise, it behaves as a pan.

Additionally, setting SoftInputMode at the sample level does not apply to the dialog.

Description of Change

• Retrieve the SoftInputMode from the Context and apply it to the dialog. This ensures consistent behavior and proper functionality, even when SoftInputMode is set at the sample level.

Regressed PR

• Use DialogFragment for Android modals #22869 -- Initially, DecorView was used for modal pages, but it has now been replaced by DialogFragment for improvements.

Issues Fixed

• Fixes [Android] WindowSoftInputModeAdjust is not working for modal pages #27242
• Fixes After rotating the 'Edit recipe' to horizontal position and trying to edit, the page shouldn't have color bars. #27240

Tested the behaviour in the following platforms

• Android
• Windows
• iOS
• Mac

• The method name 'WindowSoftInputModeAdjustSetToPanForModalpage' should be 'WindowSoftInputModeAdjustSetToPanForModalPage' to maintain consistency in naming conventions.
