Subject: [PATCH] feat: add Postiz bi-directional sync for campaign workflows

Connect campaign strategy builder to Postiz scheduler instances (cc, p2pf, bcrg).
Push posts to Postiz with per-platform sync state tracking, pull metrics back,
and display live sync status dots + metrics in the graph and detail panels.
