Fix 'Parentheses in (context as? Activity) are unnecessary and can be replaced with: context as? Activity' issue in app\src\main\java\com\brainer\itmmunity\componant\AppBar.kt

[CodeFactor](https://www.codefactor.io/repository/github/brainer3220/itmmunity) found an issue: Parentheses in (context as? Activity) are unnecessary and can be replaced with: context as? Activity

It's currently on:
[app\src\main\java\com\brainer\itmmunity\componant\AppBar.kt:163](https://www.codefactor.io/repository/github/brainer3220/itmmunity/source/master/app/src/main/java/com/brainer/itmmunity/componant/AppBar.kt#L163)
Commit 95569f15256f92e93b06906642316df65d6253d8

Open app/src/main/java/com/brainer/itmmunity/componant/AppBar.kt at line 163 and inspect the CodeFactor finding for the context cast. Confirm the unnecessary parentheses can be removed without changing the expression, then verify the Kotlin file still builds and the warning is gone.
