Core: Add debug flag and rename Platform to AppPlatform (#422)

### TL;DR
Added debug flag detection and improved platform-specific information handling across Android and iOS.

### What changed?
- Renamed `Platform` interface to `AppPlatform` and `getPlatform()` to `getAppPlatform()`
- Added `isDebug()` function to detect debug builds on both platforms
- Enabled BuildConfig for Android to support debug detection
- Updated `LocalPlatformTypeProvider` to use `staticCompositionLocalOf` with proper platform initialization
- Implemented platform-specific debug detection (BuildConfig.DEBUG for Android, Platform.isDebugBinary for iOS)

### How to test?
1. Build and run the app in both debug and release configurations
2. Verify that `isDebug()` returns the correct boolean value for each build type
3. Confirm platform information is correctly displayed
4. Check that platform-specific features work as expected on both Android and iOS

### Why make this change?
To provide a more robust way to detect debug builds across platforms and improve the platform-specific information architecture. This enables better debugging capabilities and platform-specific optimizations in the codebase.
