Replace Python sx_call loops with data-driven SX defcomps using map

Move rendering logic from Python for-loops building sx_call strings into
SX defcomp components that use map/lambda over data dicts. Python now
serializes display data into plain dicts and passes them via a single
sx_call; the SX layer handles iteration and conditional rendering.

Covers orders (rows, items, calendar, tickets), federation (timeline,
search, actors, profile activities), and blog (cards, pages, filters,
snippets, menu items, tag groups, page search, nav OOB).
