Eliminates all render_template() calls from POST/PUT/DELETE handlers across all 7 services. Moves sexp_components.py into sexp/ packages per service. - Blog: like toggle, snippets, cache clear, features/sumup/entry panels, create/delete market, WYSIWYG editor panel (render_editor_panel) - Federation: like/unlike/boost/unboost, follow/unfollow, actor card, interaction buttons - Events: ticket widget, checkin, confirm/decline/provisional, tickets config, posts CRUD, description edit/save, calendar/slot/ticket_type CRUD, payments, buy tickets, day main panel, entry page - Market: like toggle, cart add response - Account: newsletter toggle - Cart: checkout error pages (3 handlers) - Orders: checkout error page (1 handler) Remaining render_template() calls are exclusively in GET handlers and internal services (email templates, fragment endpoints).
