Refactor Icon to use KIcon instead of VIcon

[BabyElias]

Desired behavior

Refactor the internals of the Icon component to use KIcon while preserving Studio-specific notranslate logic.

Current behavior

The current implementation of icons in the codebase relies on the usage of the Vuetify component, VIcon, within a custom Icon component. Based on a discussion in the Slack conversation with @MisRob (Slack Thread), it was suggested to refactor the Icon component to use KIcon for its implementation

TODOs (Rough) :

• Audit how Icon is used and preview all places where it is used
• If needed, update KIcon
• Refactor Icon to use KIcon for internal implementation
