GetUserOrLinkShareUser re-fetches the account and fails its status
check, which broke deleting a disabled user's projects (the deletion
runs with the disabled account as doer). Convert the authenticated
principal directly instead — it also matches what the events serialized
before the doer became concrete, and drops a query per event.
ProjectUpdated/Deleted, ProjectSharedWith* and TeamCreated/Deleted
carried an interface-typed Doer that could not be unmarshaled, forcing
the audit registrations to decode anonymous mirror structs. Hydrate the
doer via GetUserOrLinkShareUser at the dispatch sites like the task
events already do, register the events directly and drop the untyped
audit registration path.
Webhook payloads for these events now serialize link share doers as
their pseudo-user (negative id) instead of the raw link share object,
consistent with task events.
Make isErrUserStatusError public and replace all verbose
!IsErrAccountDisabled(err) && !IsErrAccountLocked(err) checks
with the shorter IsErrUserStatusError(err) call.
