Metafield Restrictions: Not enforced on an edit that doesn’t change the state of the offending value.

Dashboard Redirects: To individual models now sort by modified by default.
- The dashboard shows new entries, making it logical to sort the list based on changes.
- Small fix to avoid sanitizing index URLs, ensuring multiple query parameters work correctly.

Alignments: Rules relaxed. (Fixes #164)
- Site admins can add alignments to anyone.
- Organization admins can add alignments for their own organization members.
- Group admins can add alignments for any of their managed organization’s members.
Authkeys: Allow for authkeys with no expiration set. (Fixes #169)
