Iterate getting started page (#244845)

## Summary

Iteration on Workplace AI getting started page.

- Remove all other details from the header; only Connection details
should remain.
- Ensure the chat interface matches the existing Agent Builder
experience.
- Add appropriate padding between sections.
- Align the header text with the updated chat interface layout.
- For My agents and My sources, display a maximum of 4 items. If more
exist, show a See all link. If fewer than 4 exist, the card should
expand to fill the space.
- Rename Snapshots to My Usage Snapshot and Usage snapshot to Chat
Activities (data can remain hardcoded).
- In My Agents, remove the type field and display the number of tools
instead.
- Refactor routes and remove create agent deep-link
