### Summary
- Add a preserveAuras flag to summon teleport helpers.
- Keep auras when using the summon command.
- Leave meeting stone behavior unchanged (auras can still be cleared
there).
### Motivation
Summon command was clearing buffs (e.g., Hellscream’s Warsong in ICC)
because auras were explicitly interrupted before teleporting. This
change keeps existing meeting stone behavior but preserves auras for the
summon path to avoid losing valid buffs.

### Testing
Go to ICC and téléport Bots
Add RemoveAurasWithInterruptFlags call before all TeleportTo operations
to prevent race condition crash in battlegrounds.
The crash occurs when area auras (like "Entering Battleground") are
queued for removal in Aura::UpdateTargetMap's targetsToRemove list,
but the unit is deleted before the 500ms update cycle completes,
causing SIGSEGV when accessing the dangling pointer.
This fix removes auras with AURA_INTERRUPT_FLAG_TELEPORTED and
AURA_INTERRUPT_FLAG_CHANGE_MAP before teleporting, matching the
behavior in Player::TeleportTo for real players.
Affected locations:
- BattleGround join/teleport
- Spirit healer/graveyard teleport
- Corpse resurrection teleport
- Meeting stone teleport
- Master follow teleport
- RPG unstuck teleport
- Random bot teleport
- Chat command teleport
Raid-specific teleports excluded as they require separate testing.
