Move events/market/blog composition from Python to .sx defcomps (Phase 9)

Continues the pattern of eliminating Python sx_call tree-building in favour
of data-driven .sx defcomps. POST/PUT/DELETE routes now pass plain data
(dicts, lists, scalars) and let .sx handle iteration, conditionals, and
layout via map/let/when/if. Single response components wrap OOB swaps.
