feat: implement dynamic platform entry point system

- Add src/main.ts as dynamic entry point that loads platform-specific code
- Update index.html to use dynamic main.ts instead of hardcoded main.web.ts
- Remove external capacitor config from vite.config.common.mts to ensure proper bundling
- Enables consistent platform detection across all build targets
- Use proper logger utility instead of console.log for platform detection logging
