giles 57a31a3b83 Convert all 23 register_custom_layout calls to register_sx_layout across 6 services
Layout defcomps are now fully self-contained via IO-primitive auto-fetch
macros, eliminating Python layout functions that manually threaded context
values through SxExpr wrappers.

Services converted:
- Federation (1 layout): social
- Blog (7 layouts): blog, blog-settings, blog-cache, blog-snippets,
  blog-menu-items, blog-tag-groups, blog-tag-group-edit
- SX docs (2 layouts): sx, sx-section
- Cart (2 layouts): cart-page, cart-admin + orders/order-detail
- Events (9 layouts): calendar-admin, slots, slot, day-admin, entry,
  entry-admin, ticket-types, ticket-type, markets
- Market (2 layouts): market, market-admin

New IO primitives added to shared/sx/primitives_io.py:
- federation-actor-ctx, cart-page-ctx, request-view-args
- events-calendar-ctx, events-day-ctx, events-entry-ctx,
  events-slot-ctx, events-ticket-type-ctx
- market-header-ctx (pre-builds desktop/mobile nav as SxExpr)

"""
Async I/O primitives for the s-expression resolver.
These wrap rose-ash's inter-service communication layer so that s-expressions
can fetch fragments, query data, call actions, and access request context.
Unlike pure primitives (primitives.py), these are **async** and are executed
by the resolver rather than the evaluator. They are identified by name
during the tree-walk phase and dispatched via ``asyncio.gather()``.
Usage in s-expressions::
(frag "blog" "link-card" :slug "apple")
(query "market" "products-by-ids" :ids "1,2,3")
(action "market" "create-marketplace" :name "Farm Shop" :slug "farm")
(current-user)
(htmx-request?)
