feat: feature gating for activity panel and automatic provisioning

[raquelmsmith]

Problem

As a follow up to the Teams plan launch, we needed to add feature gating for:

• Team activity side panel
• Automatic provisioning
  • Technically Automatic provisioning !== adding a domain. But there is no point in adding a domain without automatic provisioning, SSO enforcement, or SAML. In the billing PR linked below I made sure that these features are included together.

This requires https://github.com/PostHog/billing/pull/479 to go live first

Changes

• Blocks access to the Team activity side panel if they don't have the audit_logs feature.
  • 
• Blocks access to the "Authentication Domains" section of the org settings page
  • 
• Puts check in API to make sure people don't create domains if they don't have the feature

How did you test this code?

Updated tests. I also removed tests for self-hosted because this shouldn't be available for self-hosted.
