fix(conformance): repoint MedcareBridge import after #585 OGIT/OGAR split

#585 moved the OGAR-driven port bridges (UnifiedBridge harness +
MedcareBridge/OpenProjectBridge/RedmineBridge) from lance-graph-ontology
to lance-graph-ogar, but missed one consumer: the
lance-graph-consumer-conformance crate still did
`use lance_graph_ontology::bridges::MedcareBridge;` at lib.rs:93, which
now fails to compile (MedcareBridge no longer lives there).

Fix — the same transformation #585 applied to every other consumer:
- repoint the import to `lance_graph_ogar::bridges::MedcareBridge`
- add the `lance-graph-ogar` path dep to the crate's Cargo.toml

OgitBridge (lib.rs:222) and WoaBridge (lib.rs:331) are untouched — those
are OGIT-native legacy bridges that correctly stayed in
lance-graph-ontology. The callcenter `UnifiedBridge` (lib.rs:25) is an
unrelated type, also untouched.

No dependency cycle: conformance -> ogar -> ontology -> contract.
