Qualify colon model references against the provider registry
Splitting on the first colon in FromStr broke bare model IDs that
legitimately contain one. A reference like "llama3:8b" parsed as
provider "llama3" selector "8b", and since "llama3" is not a provider
the lookup failed instead of passing the ID through to the pinned
provider. Verified against origin/main: canonical_session_model with
"future-model:latest" pinned to openrouter returned the passthrough
before and a 400 after.

This is not fixable by choosing a different separator. Bedrock
inference-profile ARNs contain both colons and slashes, and
docs/public/integrations/bedrock.mdx tells users to put arbitrary
inference-profile IDs in api_id. Only the registry can tell a provider
prefix from a model ID that happens to contain the separator.

FromStr now leaves colon-bearing tokens bare, and ModelRef::qualify
promotes only those whose prefix names a known provider. resolve()
applies it, so the fallback path is covered; sessions.rs applies it
before its own match so it keeps its tailored ambiguity messages.

ModelRegistry is now implemented for Catalog in fabro-types, replacing
the CatalogModelRegistry wrapper that existed only in start.rs, so both
call sites share one registry view.

Covered by regression tests at both surfaces, plus qualify unit tests
for ollama tags and Bedrock ARNs. The pre-existing passthrough test
canonical_session_model_preserves_unknown_passthrough_on_selected_provider
passes again.
