jrklaus8 plugs Mike into Canadian case law

jrklaus8 has wired the chat front end to a Canada-specific backend, so a question can be sent as an ordinary matter or a tribunal matter and come back with a relevant Canadian case citation shown in its own panel. A second pass adds federal legislation from Justice Canada - the government's official statute source - marked out with its own styling.

The honest caveat: this is early. When a citation points to an external Canadian source, the app can't yet open the underlying document and shows a placeholder instead of the full text. The plumbing for fetching and labelling citations is in place; the document viewer is the gap still to close.
