[Jetlagged] Update icons and remove material icons dependency

[JolandaVerhoef]

This PR replaces the Material Icons dependency with local drawable resources for all icons used in the JetLagged sample.
This involves:

• Adding new vector drawable XML files for each icon (ic_bedtime.xml, ic_home.xml, ic_leaderboard.xml, ic_menu.xml, ic_settings.xml, ic_single_bed.xml, ic_watch.xml).
• Updating composable functions in HomeScreenCards.kt, JetLaggedHeader.kt, and JetLaggedDrawer.kt to use painterResource for loading these local drawables instead of relying on the Icons object from the material-icons-extended library.
• Removing the androidx.compose.material.iconsExtended dependency from the app's build.gradle.kts file.
• Modifying the Screen enum in JetLaggedDrawer.kt to use Int (drawable resource ID) for the icon property instead of ImageVector.
• Changing the icon parameter type in TwoLineInfoCard from ImageVector to Int.

Summary of Changes

Hello @JolandaVerhoef, 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 significantly refactors the icon management within the JetLagged sample application. The primary goal is to remove the external dependency on the Material Icons library by migrating all used icons to local vector drawable resources. This change streamlines the asset pipeline, potentially reduces app size, and provides greater control over icon customization.

Highlights

• Dependency Removal: The androidx.compose.material.iconsExtended dependency has been removed from the project's build.gradle.kts file, reducing the application's external dependencies.
• Local Icon Migration: All icons previously sourced from Material Icons have been replaced with local vector drawable XML files. New drawable resources (ic_bedtime.xml, ic_home.xml, ic_leaderboard.xml, ic_menu.xml, ic_settings.xml, ic_single_bed.xml, ic_watch.xml) have been added to the res/drawable directory.
• Composable Function Updates: Composable functions in HomeScreenCards.kt, JetLaggedHeader.kt, and JetLaggedDrawer.kt have been updated to load icons using painterResource with the new local drawable resource IDs, instead of relying on ImageVector objects from the Material Icons library.
• Type Refactoring: The icon property in the Screen enum within JetLaggedDrawer.kt and the icon parameter in the TwoLineInfoCard composable in HomeScreenCards.kt have been changed from ImageVector to Int to accommodate the use of drawable resource IDs.

Code Review

This pull request replaces the Material Icons dependency with local vector drawables. Consider using @DrawableRes annotations for type safety and removing hardcoded fillColor from the new vector drawables to ensure they are tintable and compatible with different themes.
