Space creation was broken because the canvas module has id "rspace" but
all navigation URLs used "/canvas". On production subdomain routing this
resulted in 404s after creating a space.
- Switch create-space form from deprecated /api/communities to /api/spaces
- Replace all /canvas navigation URLs with /rspace to match module ID
- Fix DID matching in space listing to check both sub and did:key formats
- Add proper client DID support in EncryptID registration flow
