[AnVIL DX] Upgrade findable-ui to v51.0.0

[frano-m]

Upgrade @databiosphere/findable-ui to v51.0.0.

Breaking change

• Make NextAuth and Google Auth integrations tree-shakeable and conditional imports (Updated tests. Resolves #707. #719, Don't send file filter (besides matrix) to Matrix Service Manifest Request #769)
  • Auth-related imports have been reorganized into lib/google/, lib/nextauth/, lib/terra/, and lib/auth/ modules
  • next-auth is now an optional peer dependency and can be removed from consumers that only use Google auth

Consumer changes required

• Update import paths for GoogleSignInAuthenticationProvider, TerraProfileProvider, GoogleProfile, and GOOGLE_SIGN_IN_PROVIDER
• Remove next-auth from dependencies (no longer needed for Google auth consumers)
