feat(notifications): complete notification delivery system with email, push, and in-app support

Add 5 new event listeners (listing.approved, listing.rejected, payment.confirmed,
subscription.expiring, inquiry.received), 3 new Handlebars templates, readAt field
for in-app read/unread tracking, unread/mark-as-read API endpoints, and unit tests.

All 57 notification tests pass, lint clean, typecheck clean.
