Migrate `AsyncDialogs` to Material 3

[neeldoshii]

Description

Currently the issue was that the colour of the checkbox was not matching with the APP theme @color/material_light_blue_500. Initially, my thought process was to add a style in the Theme to ensure the checkbox color matches the app theme. However, I later realized that migrating to Material3 would be a better approach, as it allows the checkbox color to adapt dynamically based on the app theme. Since we plan to migrate to Material3 eventually, this seems like the most forward-thinking solution.
