refactor: add world-local static plugin config, remove ContextLoadingSettings resource

[makspll]

Summary

Removes ContextLoadingSettings and instead moves its innards into a ScriptingPluginConfiguration<P> struct,
which can be accessed via P::readonly_config(world.id())

This should:

• further simplify HandlerCtxt bringing us closer to a world where we can put it in an Arc
• Speed up access to these configs, as they generally don't need to be a resource, and are only ever written to at app startup time

Migration Guide

Switch all references of ContextLoadingSettings to P::readonly_config(world.id()).

Pull Request Overview

This PR refactors the configuration system by removing the ContextLoadingSettings resource and replacing it with a world-local static plugin configuration system. The change simplifies HandlerCtxt and improves performance by avoiding resource lookups for configuration that is only set at app startup.

• Introduces ScriptingPluginConfiguration<P> with thread-local storage accessed via P::readonly_config(world.id())
• Removes ContextLoadingSettings resource and related code throughout the codebase
• Updates all configuration access patterns to use the new static configuration system
