Pulse Telos dashboard: use-telos-data.ts is an unfinished stub — always shows sample fixture data

[packetsherpa]

Bug

After running /interview and populating the TELOS files, the Telos dashboard (/telos) always displays the sample fixture data instead of the user's real content.

Root cause

Pulse/Observability/src/app/telos/_v7/use-telos-data.ts unconditionally returns the FALLBACK sample constant and never calls the API:

void version;
return { telos: FALLBACK, refetch, error: null };

The version state and refetch callback exist but are unused. /api/telos/overview is never called. Real TELOS data is completely inaccessible from the dashboard regardless of what the interview populated.

Impact

Affects any user who completes /interview and opens the dashboard — the intended first-run flow. The dashboard silently shows placeholder content with no error.

Fix

Replace the stub with a useEffect that fetches /api/telos/overview on mount and merges the real data over the fallback (using typed field mapping to satisfy required interface fields like horizon, blocks, overcomes).
