fix: reject wrong-typed embed/file page keys; author_id is-None check (v0.1.3)

- a dict page with a wrong-typed embed/embeds/file/files key now raises a clear
  paginator-side ValueError instead of forwarding it to discord.py as a conflicting
  kwarg (opaque TypeError) (L12)
- interaction_check uses 'author_id is None' so an author_id of 0 still restricts (nit).
