createDocument now queues and syncs like the other offline-capable
writes, closing the gap deliberately left open earlier this session.
Synthesizes a pending-<uuid> document (same placeholder scheme as
pin/star/subscribe), caches it so it's immediately readable/openable,
and queues the real create. On sync, the server's real document
replaces the placeholder in the cache — no dead orphan entries.
Editing that same still-unsynced document folds the edit into the
pending create's payload instead of queuing a separate update, which
would otherwise target the placeholder id and 404 forever once
flushed. CreateDocumentRequest widened Encodable -> Codable for the
queue round-trip.
Known limitation: a reader still open on that exact document at the
moment it syncs in the background keeps holding the stale placeholder
id until navigated away and back. Narrow, not solved generally here.
3 new OutlineKit tests (57/57). Removed the now-unneeded offline
restriction on the reader's New Document button/menu item.
