Hotfix for the 3.0.0 release

Additions

• Added a new ambient sound that plays when entering a world.

SCP-173

• Fixed SCP-173 moving or killing players while clearly being watched, including cases where its visible and real positions did not match;
• Neck snaps now require actual physical contact with the target, as intended;
• Limited automatic blink movement to six blocks, removed unintended extra movement, and kept manual blinking continuous;
• Fixed observation through solid blocks, facility doors, and door animations, while preserving sight through the windows in Normal and Office doors;
• Fixed SCP-173 activating or moving before being seen by a Survival player; Creative and Spectator players no longer activate it;
• Restored the natural-spawn rattle and corrected the jumpscare and blink HUD triggers;
• Fixed SCP-131 and other configured creatures sometimes failing to keep SCP-173 frozen.

Facility doors

• Fixed collision and passage for Normal, Logistics, Office, Bathroom, and Workshop doors, including mobs failing to use visibly open doorways (it's not perfect yet, because minecraft);
• Door opening and closing sounds now come from the door's position.

Decontamination Checkpoint

• Fixed players being detected outside the chamber or missed while inside it;
• Fixed repeated sounds, processing, and particle effects during the same visit, as well as checkpoints failing to reactivate after players left;
• Improved the decontamination gas so it lasts for the full cycle and smoothly fills the chamber from the floor grilles.

Audio and presentation

• Rebalanced the volume of facility, SCP, terminal, and machine sounds;
• Fixed SCP-131 idle and movement sounds stopping, overlapping, or losing their position;
• Fixed the missing lang for Playing Card;
• Fixed Playing Card, Credit Card, Pieces of Paper, Coin, and Paper Cup appearing under Spawn Eggs tab; they now appear in SCP Additions Misc tab.

SCP Inventory and items

• Fixed Tesla Gate Terminals failing to recognize Security Credentials stored in SCP Inventory;
• Fixed SCP-294 coins being lost or consumed incorrectly;
• Fixed equipped weapons returning to SCP Inventory after a durability-changing hit.

Other fixes and adjustments

• Reduced how often SCP-079 attempts to control facility doors;
• Fixed saved Tesla Gates remaining stuck in a shock animation;
• Fixed Tesla Gates failing to respond to their terminals;
• Fixed the SCP-914 death sound playing for Coarse outcomes;
• Fixed the Decontamination being stuck locked after leaving the world while inside of an active one.
