Blacklist apexgunparts.space for newsletter subscriptions

[Copilot]

Spam signups were coming from apexgunparts.space, which was not covered by existing domain-based filtering. This PR extends the newsletter spam-domain blacklist to block that domain consistently across subscription paths.

• Blacklist update

  • Added apexgunparts.space to the centralized BAD_DOMAINS list used by newsletter subscription filtering.

• Behavior coverage

  • Extended unit coverage to assert this domain is treated as spam by:
    • emailIsBad(...)
    • fakeSubscribe(...)
    • subscribe(...) (returns the same fake-success response used for blocked domains)

const BAD_DOMAINS = ['mailinator.com', 'abhoward.site', 'apexgunparts.space'];
