There is a need to remove FluentValidation on ComponentBase disposed

Fix for #155 #93

[teneko]

This solution has several issues:

1. It introduces a potential hidden breaking change if EditContext ever implements IEquatable or overrides GetHashCode.
2. It shifts state management to a static context, breaking the logical binding to a single FluentValidationValidator instance.
3. If two separate FluentValidationValidator components are used with the same EditContext, event unregistration is handled in a first-in-first-out manner rather than by identity, which can lead to incorrect behavior.
