Add Links to WorkGraph Table, Data Node Table, and Settings on the Homepage

[superstar54]

Currently, the homepage of the frontend is empty, which can make navigation less intuitive for users. To improve usability, we should add the following links to the homepage:

• WorkGraph Table
• Data Node Table
• Settings
• Also add useful links to docs, and AiiDA related

Design and Layout:

• determine the best layout for adding these links to the homepage (e.g., buttons, cards, or a simple list).
