Subject: [PATCH] feat(afc): gate lane eject on mounted tool

Add an optional `mounted` flag to the AFC lane type and drive the lane
Eject button's disabled state from it: when the backend reports it, Eject
enables only for the lane whose tool is on the carrier. When `mounted` is
absent it falls back to the exact previous expression, so behaviour is
unchanged for backends that don't report it.

This is to allow for better control of multi-tool machines.
