giles d53b9648a9 Phase 6: Replace render_template() with s-expression rendering in all GET routes
Migrate ~52 GET route handlers across all 7 services from Jinja
render_template() to s-expression component rendering. Each service
gets a sexp_components.py with page/oob/cards render functions.

- Add per-service sexp_components.py (account, blog, cart, events,
  federation, market, orders) with full page, OOB, and pagination
  card rendering
- Add shared/sexp/helpers.py with call_url, root_header_html,
  full_page, oob_page utilities
- Update all GET routes to use get_template_context() + render fns
- Fix get_template_context() to inject Jinja globals (URL helpers)
- Add qs_filter to base_context for sexp filter URL building
- Mount sexp_components.py in docker-compose.dev.yml for all services
- Import sexp_components in app.py for Hypercorn --reload watching
- Fix route_prefix import (shared.utils not shared.infrastructure.urls)
- Fix federation choose-username missing actor in context
- Fix market page_markets missing post in context

Federation App

OAuth2 authorization server and ActivityPub social hub for the Rose Ash cooperative. Handles user authentication, fediverse federation, and social features (timeline, compose, follow, notifications).

OAuth2 SSO

Federation is the authorization server for all Rose Ash apps:

  • /oauth/authorize — authorization endpoint (PKCE supported)
  • Magic link login (passwordless email)
  • All client apps auto-get /auth/login, /auth/callback, /auth/logout via shared/infrastructure/oauth.py
  • Per-app first-party session cookies (Safari ITP compatible)

ActivityPub

  • Per-app actors: each app has its own AP actor (virtual projection of the same keypair)
  • Actor endpoints: webfinger, actor profile, inbox, outbox, followers
  • Social features: timeline, compose, search, follow/unfollow, like/boost, notifications
  • Activities emitted to ap_activities table, processed by EventProcessor
  • HTTP signatures + IPFS content addressing

Cross-domain communication

  • services.blog.* — post queries for content federation
  • services.calendar.* — event queries
  • services.market.* — product queries
  • services.cart.* — cart summary for context processor
