Add commands to resume and view payjoin history

Add commands to resume and view payjoin history

Expose persisted payjoin session state through CLI commands so users
can recover interrupted sessions and review prior session progress.
Add `resume` to continue pending sender and receiver sessions,
`history` to list saved sessions, status text helpers for clearer
output, and session ID filtering to target a specific session.

This improves recovery and troubleshooting for long-running async
payjoin flows by making persisted session state available from the
CLI.
