[Antreesy]

☑️ Resolves

• Fix duplicated requests and reloads, if different federated rooms belong to the same remote server

🖌️ UI Checklist

🖼️ Screenshots / Screencasts

Added some logs for visibility:

• for clean storage or new server - works as before, asking to reload the page
• for next, if server matches - update token map, cache new token for future
• in Network - no new requests for 'capabilities'
