[FIXED] [CoS] Opening the door after RP event

[FreakzStaff]

1. Opening the door leading to the 3rd boss in CoS should take 10 seconds. Currently it's an instant cast. [Retail proof]( https://youtube.com/watch?v=Zpz7oCal18E:

)
2. The door leading to the 3rd boss in Court of Stars should only be clickable after killing the Suspicious Noble and one of the party members looting his keys. On live there is no such requirement, the door can be clicked as soon as the mini-boss dies. [Retail proof]( https://youtube.com/watch?v=nbyKq2oc1eI&t=1288:
