Count processed/failed indexer events in the Soroban worker and expose them on /health and admin metrics so a broken indexer cannot look healthy when lag stays low. Also restore a broken SSE merge and align Vitest coverage peer deps so the suite can run. Closes LabsCrypt#844 Co-authored-by: Cursor <cursoragent@cursor.com>
