docs: add control interface link and sleeping Space guidance

- Add direct link to the control interface in the install page setup
steps (the main gap Matthieu hit — page never told users where to go
to actually control the robot)
- Clarify the two URLs: wss:// for robot settings, https:// for browser
- Add sleeping Space note (48h inactivity, wait ~30s before robot connects)
- Fix README Step 4 placeholder URL → actual HF Space URL
- Fix default profile example in README (was showing localhost)
- Add HTTP 429 troubleshooting entry (sleeping Space) to README
