feat: embeddable routes

[TorstenDittmann]

The changes in this commit refactor several console pages by extracting the main UI logic into separate view components. This allows the same views to be reused between the main console and embedding contexts.

Key changes:

• Move page content into view components for auth, database, messaging, and storage sections
• Add embedded versions of pages that reuse the view components
• Update layout configurations to support embedding
• Add new studio theme variations for embedded context

The refactoring improves code reuse and maintainability while enabling the same UI components to be used in different contexts.
