docs: align Space description with current behavior

- Remove references to 'Recover a previous job' panel (deleted earlier)
- Remove obsolete 'live polling every 8s' / 'WebSocket disconnect' warnings
- Acknowledge backend can be ibm_kingston OR ibm_fez (least-busy Heron)
- Direct users to IBM Quantum Workloads dashboard as source of truth
