Removes the dedicated `HomePage` and its associated model files.
Configures `ReceptionPage` as the new default landing page after successful login and product form submission. Updates navigation and state management dependencies to direct users to the primary operational interface upon entry.
Moves page files from verbose `*_page` named directories to simpler, more organized paths.
This includes:
- Renaming top-level pages (e.g., `home_page` to `home`, `login_page` to `login`).
- Nesting related pages under common directories (e.g., `product_form_page` and `product_list_page` are now under `product/`).
The update improves project organization, reduces verbosity in file paths, and enhances overall maintainability.
