Fix page editing: use Ghost /pages/ API for pages, not /posts/

Ghost has separate /posts/ and /pages/ endpoints. All admin functions
(get_post_for_edit, update_post, update_post_settings, sync) were
hardcoded to /posts/, causing 404s when editing pages. Now checks
is_page from post_data and uses the correct endpoint.

Also uses sync_single_page (not sync_single_post) after page saves
to prevent IntegrityError from mismatched fetch/upsert paths.
