feat: auction-won / auction-ended / offer-expired notifications

Plug the remaining state-machine gaps the previous notification
batch left dark. With auction_tick and offer_tick running on cron,
buyers and sellers now learn about every passive transition:

- auction_tick ACTIVE → ENDED (with winner) drops
  notify_auction_won for the winner — they see the pay CTA + 48h
  payment_deadline before it lapses. Previously only the email
  fired (and only if SMTP succeeded); now the in-app row also
  exists with breadcrumbs Shop → Product → Auction.
- auction_tick ACTIVE → ENDED (without winner / reserve not met)
  drops notify_auction_ended_no_winner for shop owners so they
  can decide to relist.
- offer_tick PENDING/COUNTERED → EXPIRED and ACCEPTED → EXPIRED
  both drop notify_offer_expired for buyer + shop owners. The
  buyer was the most-affected silent case: they made an offer,
  the seller never responded, the offer auto-expired, the buyer
  never knew.

Four new notification kinds in models/notification.py:
auction_won, auction_ended_no_winner, auction_cancelled
(reserved — no call site yet), offer_expired.

lib/notifications.py orchestrator refactored: _resolve_session()
accepts either a Pyramid request or a SQLAlchemy session so the
same helpers work in views AND tick jobs.

Integration tests in TestAuctionTickIntegration and
TestOfferTickIntegration assert the right row exists with the
right kind + FK after each tick.
