Remove `any` types from `@console/` package

[jeroenrinzema]

Description

ESLint is currently informing us about any types throughout the frontend. These need to be replaced with proper type definitions.

Requirements

• Replace all any with actual types (interfaces, unions, generics, etc.)
• Do not use type assertions (as) as a workaround — fix the underlying type issue
• Scope: Frontend only (backend isn't TypeScript anyway)

Acceptance Criteria

• npm run lint passes with no any-related errors
• No as type assertions added
