manager: surface D-Bus call errors to the user

Browse source 
Connect / Forget / Set(Powered) / Scan / Disconnect / RegisterAgent /
ConnectHidden previously discarded reply errors with NULL callbacks, so
"Connecting…" could hang forever after a refused call (rfkill, busy
adapter, another agent already registered, bad credentials on a known
network). The user had no way to see the failure.

Add iwd_manager_{report,last,clear}_error and wire reply callbacks in
adapter / device / network / agent. The popup status line now appends
the latest error to the state label, and user actions (rescan, toggle,
connect, disconnect) clear it.

Scan errors that mean "already in flight" are filtered out — they're
the normal race when two scan triggers fire close together.
