fix: detect article/note post type via permalink for AI frontmatter

Indiekit's getPostTemplateProperties() explicitly removes the post-type
property before passing JF2 to postTemplate(). The v3 patch relied on
post-type to set supportsAiDisclosure, which was therefore always false —
causing the ai: frontmatter block to never be written regardless of what
was selected in the backend form.

v4 patch falls back to permalink URL pattern (/articles/, /notes/) to
correctly detect the post type when post-type is absent.
