[Enhc]: Standardize design across project with style refactor and folder reorg.

[Spiral-Memory]

As an EmbeddedChat developer, I need to:

Refactor stylings, remove all module.css files, add component.style.js files to separate styling while still utilizing Emotion CSS. Additionally, I need to reorganize folders, separating core components into src/components and other large components specific to EmbeddedChat into src/views.

So that:

The codebase is more organized, modular, and easier to maintain.

Acceptance Criteria:

• [x] Refactor stylings
• [x] Remove module.css
• [x] Add component.style.js
• [x] Folder reorganization
