fix(epay-ui): stuck connect spinner + order button shows processing not instant-valid

Two UX issues reported from the field:

1. ePay pill spun forever on an already-connected (green) pill. Two causes:
   the icon put connecting before connected (so a stuck connecting state
   showed the spinner even when connected), and the auto-connect effect leaked
   the connecting state — a cancelled early-return skipped clearing it, and
   having connecting in the dep array made setConnecting(true) cancel its own
   in-flight attempt. Fix: connected takes icon priority; a finally{} always
   clears connecting unless retrying; drop connecting from deps.

2. The per-parcel CF button flipped straight to green "Extras CF valid" the
   instant the order was queued, while it actually kept processing ~1-2 min in
   the background (cart, submit, poll, download). Now it shows a pulsing
   "Se proceseaza..." and polls until a completed extract truly exists before
   flipping to valid.
