fix: minor Android Studio warnings

[aadityarshah]

Purpose / Description

As a new contributor, I wanted to get familiar with the codebase and wanted to have my first pull request merged. Fixes #13282 seemed to be a good starting point and hence, I decided to fix some Android Studio warnings.

Fixes

• Fixed a problem/error in 1 file (AnkiDroid/src/test/java/com/ichi2/anki/CardBrowserTest.kt)
• Fixed simple warnings in 3 other files

Approach

Ran Code/Inspect Code in Android Studio and reviewed the warnings/problems in the code and made the following changes:

• In CardBrowserTest.kt in the directory AnkiDroid/src/test/java/com/ichi2/anki, added a space between 'current' and 'use' since it was a problem in the file
• In AnalyticalWidgetProviderTest.kt in the directory AnkiDroid/src/test/java/com/ichi2/anki/widget and Utils.kt in the directory AnkiDroid/src/main/java/com/ichi2/anki/dialogs, added the package com.ichi2.anki ... line to resolve the warning "Package directive does not match the file location"
• In Test21And26.kt in the directory AnkiDroid/src/test/java/com/ichi2/compat, removed the redundant inner call on the class PermissionDenied.

How Has This Been Tested?

• ./gradlew assembleDebug was ran using OpenJDK 24 version on Windows 11 and since it executed successfully, it was concluded that the changes have worked successfully.
• Checked by deploying the :AnkiDroid module to an emulator which ran successfully

@aadityarshah It is not a review. But you do not have to omit items that are not ticked in the checklist.

Also, have you noticed that it has failed Unit Tests?

[aadityarshah]

@Alok-Silswal Thank you for notifying me about the fact that we do not have to omit items that are not ticked in the checklist.
I am working on resolving the error that occurred during the unit tests.
