Stub Firebase modules during server-side build

Browse Source 
Next.js evaluates all modules during build for page data collection,
including the layout which transitively imports Firebase through
@luxfi/ui and @hanzo/auth. Firebase's initializeApp() fails because
real credentials aren't available at build time.

This adds webpack aliases that redirect Firebase imports to a stub
module during server-side production builds. The real Firebase modules
still load normally in the browser at runtime.
