ref(deps): Upgrade to iroh 0.4.0 (#4245)

This moves us back to a released version;

- Ticket is now opaque, need to use accessor functions.

- Ticket now ensures it is valid itself, no need to inspect it's
  inners.  Deserialisation would fail if it was bad.

- The git version was accidentally used with default-features enabled
  and thus pulled in a few too many dependencies.  They are now gone.
