Remove deprecated statusBarColor usage (edge-to-edge already enabled)

---

Description

Hi team,

The basic-android-kotlin-compose-training-lemonade project is already using the modern edge-to-edge approach, so the explicit use of the deprecated
window.statusBarColor API in Theme.kt is no longer necessary.

---

Current Issue

• Project: basic-android-kotlin-compose-training-lemonade
• File: app/src/main/java/com/example/lemonade/ui/theme/Theme.kt
• Uses deprecated API: window.statusBarColor
• Triggers Android Studio deprecation warnings
• Redundant since edge-to-edge handling is already in place

---

Proposed Change

• Remove the deprecated window.statusBarColor call from Theme.kt
• Keep existing edge-to-edge behavior unchanged
• Preserve proper status bar icon appearance (light/dark)

No new edge-to-edge setup is required, as the project already follows the modern approach.

---

Benefits

• Eliminates deprecation warnings
• Keeps the codebase clean and future-proof
• Aligns with current Android & Material 3 guidelines
• Improves code quality for learners using this sample

I have signed the CLA and would be happy to work on this cleanup if the maintainers agree this is a welcome change.

Thank you for your time!
