feat: preconditions improvements (#1983)

* feat: implement missing precondition types (20, 21, 23) and pet checks

Add DoesNotHaveFlag (23), NotFreeTrial (20), and MissionActive (21) to
PreconditionType and implement their checks. Also implement PetDeployed
and IsPetTaming using PetComponent static helpers, matching client
behavior — both are simple boolean checks with no LOT comparison.
LegoClubMember is set to always pass as DLU has no membership concept.

* fix: update TODO comments for team check and racing licence preconditions

* type
