What Does This PR Do

PR fixes #28022
PR fixes #28056

PR #25078 introduced a few bugs related to AI eyes, mechs, and holograms, which are referenced in #28022. This change fixes those bugs.

• Entering a mech with an active hologram eye will now release that eye before granting control of the mech.
• Double clicking on a turf as an AI while in a mech will no longer unstick the camera from the mech.
• When exiting a mech, the AI will now properly refocus on its core instead of on the spot that it first entered the mech.
• AI will no longer receive duplicate original audio from holopads, and now will receive only relayed speech.
• AIs will no longer be able to activate a holopad while occupying a mech.

Why It's Good For The Game

Bugs are bad. Fixing them is good.

Testing

I booted up a test server and logged in as an AI. I spawned a phazon mech, and used VV to add an AI tracker to its trackers.

I took control of the mech, and then tried to use a holopad, to no effect. I also tried to double click on a turf, to no effect.

I navigated to another area as the mech.

I then used the eject button to eject from the mech. My camera was refocused on my core, and when I moved away from it, its movement was natural and did not jump to the location that the mech was first entered.

I activated a holopad. I then took control of the mech. The hologram disappeared. I ejected from the mech, and my camera was refocused on the core, and when I moved away from it, its movement was natural, as above.

I logged into the test server with another client as a guest. I joined as a botanist, and jumped to the central primary hallway above the bridge. On the client that I was logged in as an AI, I activated the holopad there. I spoke using departmental radio (:h) as the AI. The botanist client heard the hologram. (S.O.P.H.I.E. states, "Hello world.") I spoke normally as the botanist. The AI client heard the relayed speech only. (Relayed Speech: Lando Riker says, "Hello world.")
