Fresh cmake configures pick up APP_VERSION/API_KEY from environment
variables (as nix develop and CI provide them); -D still wins on
reconfigure. Also normalizes indentation in the sd-bus blocks.
parseAccessPoint() is extracted from an anonymous namespace so the pure
property->AccessPointInfo mapping is testable. getAccessPoints() now reads
the Flags/WpaFlags/RsnFlags properties (they were never read, so every
network was reported Open and connections lacked a security section) and
fixes the double container-enter on the SSID 'ay' read that silently
emptied the scan list.
