Add a global sound when anyone uses the door and let springtrap always know what doors were used

SpringMyTrap

1. Anytime anyone at any moment uses the door system for mobility a global sound cue plays. Not loud, but distinct and obvious enough.
2. Optionally, there should also be a visual effect tied to the doors / auras for the HoH people like the aura changing or some visual lement on the doors observable from any angle.
3. Anytime survivors use the doors, Springtrap sees the auras of the used doors in yellow regardless of whether or not he is inside the doors.

What this accomplishes:

• Gives survivors more clear and telegraphed warning that Springtrap went through the door, meaning he has to pick between immediately pressuring the generator or trying to ambush it.
• Creates a false sense of security in combination with preexisting counterplay - survivors see the springtrap is not teleporting to THEIR door, calm down only to get ambushed.
• Encourages making a use out of the long undetectable status effect
• Gives cameras more clear gameplay purpose - combat springtrap sneaking up on generators with long undetectable
• Gives a clue to when use the cameras to combat the undetectable instead of having to kinda guess it - hear the clue, wait a few seconds, hop on cameras for a slice of fnaf gameplay
• Adds a realistic risk to using the doors - instead of just using them without care, you need to use them whenever springtrap is NOT within a few seconds of reaching the door and grabbing you because there is no longer an element of hyperspecific timing and wild guess or camping for the grab to happen. It will be entirely about a short race instead which would be way more interactive and thrilling because both you and killer would be aware of the door being used.
• This could lead to some interesting plays like baiting killer to try to go for the grab but barely miss it because you timed it right when they were far away.

I think this would be a fun and healthy improvement that addresses these aspects of his kit to push them into more interactive way. His map mobility would have more distinct gameplay and survivors having doors as mobility won't be as free as it is now if we put bugs aside.

Plus it'd be pretty accurate to fnaf where a lot of things are done in a telegraphed way and the skill expression is less about "guesswork" and more about managing things correctly.
