feat: add quiet hours for ads

[RohitKushvaha01]

This PR mutes ads if the app is launched between 10 PM and 5 AM. During this time, any video ads will have their volume set to zero, though this is not guaranteed. This may also affect the eCPM of ads during this time range, as already discussed.

Closes #1293

Summary of Changes

Hello @RohitKushvaha01, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request integrates a user-centric feature that automatically mutes advertisements during specified 'quiet hours' to prevent disturbances. By configuring the AdMob SDK to respect these times, the application aims to provide a less intrusive experience for users, particularly during late-night or early-morning usage.

Highlights

• Quiet Hours Logic: Introduced a new feature to define and detect 'quiet hours' between 10 PM and 5 AM based on the current local time.
• Ad Muting: Implemented AdMob configuration to automatically mute application ads and set their volume to zero during the detected quiet hours, enhancing user experience.

Code Review

This pull request introduces a 'quiet hours' feature to mute ads between 10 PM and 5 AM. The implementation is straightforward and correct. My main feedback is to replace the hardcoded start and end hours with named constants to improve code readability and maintainability. This also makes it easier to adjust these times in the future or expose them as user settings.
