The GlobalBlocking log contains entries for when a user globally blocks or modifies an existing global block. These entries often contain flags. To support T17273, the logs will indicate whether the block disallows account creation so that it is similar to the local block log,
This means that all existing log entries should now have a account creation disabled flag to indicate that they disallowed account creation.
Acceptance criteria
- Update the GlobalBlockLogFormatter to display whether the blocks disallowed account creation
