Add component deps to page registry, check before client routing

Browse Source 
Each page entry now includes a deps list of component names needed.
Client checks all deps are loaded before attempting eval — if any
are missing, falls through to server fetch with a clear log message.
No bundle bloat: server sends components for the current page only.
