Delete events sx_components.py — move all rendering to sxc/pages

Phase 7 of the zero-Python-rendering plan. All 100 rendering functions
move from events/sx/sx_components.py into events/sxc/pages/__init__.py.
Route handlers (15 files) import from sxc.pages instead.
load_service_components call moves into _load_events_page_files.
