Fix nextjs localstorage issue

[chakra-guy]

Explanation

Fixed a critical issue with Next.js 15+ server components where the SDK would attempt to access localStorage in non-browser environments, causing runtime errors. The bug was occurring because the storage manager was unconditionally initialized with browser-specific storage, even in server-side contexts.

The solution:

1. Made PlatformManager environment detection methods static for better reusability
2. Added environment-aware storage manager initialization that returns:
   • Regular storage manager for browser environments
   • No-op implementation for non-browser environments (server-side, SSR)

Example error that this fixes:

ReferenceError: localStorage is not defined
    at StorageManagerWeb.getPersistedChannelConfig

This change ensures the SDK works reliably in all Next.js environments while maintaining full functionality in browser contexts. The no-op storage manager gracefully handles all storage operations when running server-side, preventing runtime errors without requiring changes to application code.
