[BUG] /remote-control crashes after hibernation: Cannot read properties of undefined (reading 'session_url')

What's Wrong?

After the machine hibernates with an active Remote Control session, the local registration record is lost. Running /remote-control then fails with:

Remote Control failed to disconnect: Cannot read properties of undefined (reading 'session_url')

The disconnect path dereferences the registration object without checking it exists. Meanwhile the phone-side session is stranded (shows only in Archived, frozen view still claiming a running process; permission prompts render desktop-only).

What Should Happen?

Missing registration treated as "not connected": clean up local state and offer fresh registration instead of throwing a TypeError.

Steps to Reproduce

2. Hibernate the machine overnight
3. Wake, run /remote-control in the same session
