fix(push): wait for active SW before subscribe + log every step (subscribe was failing silently)

Browse Source 
subscribePush() swallowed all errors, so if pushManager.subscribe() failed
(e.g. called before the service worker was active) nobody ever subscribed and
there was no trace. Now: await serviceWorker.ready before subscribing, and
console.log/warn each step so the real failure is visible. Server send path
verified independently (web-push builds valid VAPID requests).
