Subject: [PATCH] feat: fire PARTY_LEADER_CHANGED event on leader changes

Fire PARTY_LEADER_CHANGED (with GROUP_ROSTER_UPDATE) from both:
- SMSG_GROUP_SET_LEADER: when a new leader is named by string
- SMSG_REAL_GROUP_UPDATE: when leader GUID changes via group update

Used by raid frame addons to update leader crown icons and by
group management addons to track leadership changes.
