feat: unify page-type and custom-type into single type command

[angeloashmore]

Resolves: #96

Description

Unifies the separate page-type and custom-type top-level commands into a single type command. This avoids agents misusing custom-type for pages by providing a --format flag on create.

• prismic type create <name> creates a custom format content type (default)
• prismic type create <name> --format page creates a page format content type
• prismic type list shows all content types with format in output
• prismic type view/remove work regardless of format
• Field targeting simplified to --to-type/--from-type
