When a club has no curated routes or a chat channel has no messages, the data layer
returned fixture content with no indication it was sample data, so riders could mistake
MotorSignal's "Coastal Marshes" route or canned chat messages for their club's real data.
Flag fixture-sourced content and label it in the UI:
- Add isExample to ClubRoute and ChatMessage; set it on every fixture fallback path
(empty Firestore collection/channel and the dev demo preview).
- Founder Routes: amber "Examples" count, an explanatory banner, and a per-card "Example"
badge when the routes shown are samples.
- Founder Chat: an "Example thread" pill (instead of "Live Connected") and a banner when
the only messages are examples, so the header never claims a live conversation that
does not exist.
Tests: example-labelled routes render the banner/badge/count; example-labelled chat
renders the banner and "Example thread" pill and does not claim "Live Connected".
Existing route/chat tests (real data, no isExample) remain green.
