Fix canonical type cartouche names

[witbrock]

What changed

• Resolve subtype, instance, and direct-type labels from canonical relation-backed hasName values in one batch.
• Preserve authored acronyms and Unicode exactly, with automatic bidirectional text direction in the UI.
• Remove GET-time persistence of identifier-derived display guesses.
• Remove the ASCII CamelCase rewrite from inline name editing.

Root cause

The affected list projections ignored canonical hasName relations and reconstructed labels from lossy identifiers with title-casing. That turned identifiers such as current_uo_asail_ph_d_student into Current Uo Asail Ph D Student. The name editor could independently split UoA and PhD when merely opened and blurred.

User impact

Type cartouches now show the stored canonical names, including acronyms and multilingual Unicode text, without inventing spaces or changing code points. Ordinary subtype and instance reads no longer mutate ontology names.

Validation

• 17 focused backend tests passed; one unrelated known metadata assertion was excluded.
• 18 focused frontend tests passed.
• Ruff, Python compilation, JavaScript syntax, and git diff --check passed.
• Frontend static lint completed with 0 errors and 13 pre-existing warnings.
• Isolated AgentTest API and Playwright replay showed Current UoA SAIL PhD Student, Current UoA PhD Student, and UoA CS PhD Student, with word-spacing: 0px and dir=auto.
