feat(dashboard): Add navigation links

The "page.tsx" component in the dashboard section has been updated to include navigation links. Changes include:

- Added import statements for the "Link" component from Next.js.
- Updated the component structure to use CSS grid with 12 columns.
- Added a left sidebar with links for different sections, such as "Database," "Team Members," "Users," and "Permission."
- Added a main content area with a heading "Dashboard."

These changes aim to enhance the user experience by providing navigation options within the dashboard page.
