Modal SSID + optional passphrase prompt with the same callback shape as
wifi_auth_prompt. Used by the upcoming popup "Hidden..." button.

e_gadcon_popup hosts a status label, a scrollable list of networks
(snapshotted from iwd_manager and sorted: connected → known → alpha),
and Rescan/Enable/Disable action buttons. Clicking a network calls
Network.Connect; iwd then asks our Agent for a passphrase, which is
routed to a modal elm_popup via iwd_manager_set_passphrase_handler.
The passphrase handler is installed at module init so iwd-initiated
auth works even when the popup is closed.

Meson build, module entry points, and stub layout for the iwd backend
(D-Bus client, gadget, popup, config, UI widgets). Bodies are TODOs;
this compiles against EFL/E headers but performs no D-Bus work yet.
