feat: implement skeleton loading states for data-heavy pages

[yash-pouranik]

Description: Currently, pages like Analytics.jsx and Database.jsx display a blank screen or a simple "Loading..." text while fetching data from the backend. This can feel abrupt for users on slower connections.

Suggested Tasks:
Replace "Loading..." text with animated Skeleton components (using a library like react-loading-skeleton or custom CSS).

Implement skeletons for:

• Project cards on the Dashboard.
• Usage charts on the Analytics page.
• Data tables in the Database view.
