fix: suppress ECONNRESET noise from Funkwhale API calls

Add ECONNRESET to sync.js network error guard (was only ECONNREFUSED/
ENOTFOUND/ETIMEDOUT). Add ECONNRESET fallback in now-playing and
listenings controllers — returns graceful empty response instead of
logging console.error on transient connection resets.
