fix: android native theme sync

[Rohit3523]

Proposed changes

This PR addresses an issue where Android native components display themes based on the operating system's settings, which may differ from the app's chosen theme. The implementation introduces a native module that synchronizes the app's theme with system settings, ensuring consistent visual rendering across all app components.
Additionally, this pull request modifies the modal text and background color to align with the active app theme.

This change is still pending for iOS because I couldn't work on the native code due to issues building the debug version caused by the Xcode version.

However, support for Xcode 16.2.0 was recently added, so I'll resume work soon.
