Expose add_to_blog, new_role, and blog_id fields in signup list and get

[swissspidy]

Exposes add_to_blog, new_role, and blog_id as available fields for wp user signup list and wp user signup get, and enables filtering by them.

• Unserializes signup meta properties so add_to_blog and new_role are accessible as fields.
• Aliases add_to_blog and blog_id to allow querying and filtering by either name.
• Updates filtering logic in Signup_Command::list_() to support filtering by --new_role, --blog_id, and --add_to_blog.
• Added acceptance test scenarios covering field output and filtering.

Closes #629

📝 Walkthrough

Walkthrough

Signup_Command now exposes normalized add_to_blog, new_role, and blog_id fields, supports filtering and pagination by them, and formats retrieved signups consistently. Signup feature coverage validates the new behavior and updates wp eval quoting across existing scenarios.

Changes

Signup metadata exposure

Layer / File(s)	Summary
Normalize signup metadata and output fields src/Signup_Command.php	Serialized signup metadata is promoted to top-level fields, blog identifiers are synchronized, and get uses an object for field selection and formatting.
Filter and validate signup fields src/Signup_Command.php, features/signup.feature	Listing filters prepared signup records by new_role, blog_id, and add_to_blog, applies pagination after filtering, and feature scenarios validate listing, retrieval, pagination, filtering, and updated command quoting.
