Convert last Python fragment handlers to SX defhandlers: 100% declarative fragment API
- Add dict recursion to _convert_result for service methods returning dict[K, list[DTO]]
- New container-cards.sx: parses post_ids/slugs, calls confirmed-entries-for-posts, emits card-widget markers
- New account-page.sx: dispatches on slug for tickets/bookings panels with status pills and empty states
- Fix blog _parse_card_fragments to handle SxExpr via str() cast
- Remove events Python fragment handlers and simplify app.py to plain auto_mount
