fix: post-rebase fixes for WASM build

- Remove duplicate methods from shared files (mountTechnicalDebug,
  mountBusinessDebug, determineCurrentNetworkStatus,
  checkStorageIncentivesAvailability) - kept in platform-specific files
- Remove unused imports after method removal
- Fix ultra-light node startup by wrapping IsSynced check in chainEnabled
- Update hive.New call to include swarmAddress parameter
- Add test underlay for browser light nodes in handshake
