Fix load_service_components path for sx, market, events

The load_service_components call used dirname twice from
sxc/pages/__init__.py, yielding {service}/sxc/ instead of
{service}/. This meant {service}/sx/*.sx files (layouts, calendar
components, etc.) were never loaded into the component env.

- sx: ~sx-layout-full not found → Unknown component on client
- events: ~events-calendar-grid not found → Unknown component
- market: also fix url_for endpoint for defpage_market_admin
  (mounted on app, not blueprint — no prefix needed)
