@MohitMaliFtechiz
Sorry for the delay and not able to contribute in other Prs i was prioritizing this migration it was difficult because of many classes which required understanding.
This is an initial commit ill later add test cases too for now please review the logic.

I have added comments to help other read the code, also from previous migration i have implemented your points so it saves time.

Migration covered these parts-

• Hotspot now use composable lifecycle
• Merged Di and common fragment files and updated in ViewModel itself
• Handled Playstore and custom apps logic
• Permission block kept the same
• Instead of suppressing i made small code blocks.
• for the checkbox i modified the logic cause it wasn't updating its state with toggleSelection.
