Refactor socket

[Vitroze]

Summary

In this PR, the socket code has been completely rewritten from scratch.
It eliminates the need for timers and Think hooks (except in dev mode) in favor of the Touch function.

Features

• Creation of a dedicated Socket entity for better socket behavior management.
• Uses the Touch function instead of a timer to locate the nearest socket.
• Micro-optimization regarding entity removal.
• The vehiclesWithSockets table is retained for backward compatibility but is not used in Glide.
• Added the radius argument to the socket, allowing the detection zone to be configured.

Dev Mode

• Dev mode logic is currently implemented directly within the entity's Think function; this will be reworked in a future PR to use a timer that is created or destroyed based on the activation or deactivation of the developer convar.

I think the only breaking change here is that ENT:InitializeSockets( socket ) copies the properties from a socket by value, so editing a vehicle's ENT.Sockets won't apply the changes right away, and requires respawning the vehicle

Also InitializeSockets (plural) is a bit of a misnomer since it handles one of the sockets from ENT.Sockets, not the whole table

InitializeSockets

Essentially, it just calls the ENT:InitializeSockets function, and the problem will be resolved.

However, if you really want full compatibility without calling that function, I can make a modification if you like.

I’ve changed it, the name was indeed quite misleading.
