+Tests for encrypted IFAC values surfaced via interface discovery announces.
+
+When an upstream interface is configured with publish_ifac = yes, RNS embeds
+the network_name (ifac_netname) and passphrase (ifac_netkey) into the
+discovery announce payload, plus a ready-to-paste config_entry block. These
+tests verify that:
+
+1. The /api/v1/reticulum/discovered-interfaces endpoint passes those fields
+   through to the frontend with both the raw RNS keys and the canonical
+   config-style aliases (network_name/passphrase).
+2. ReticulumMeshChat.normalize_discovered_ifac_fields handles bytes payloads,
+   missing values, and non-list inputs without raising.
+3. discovery_filter_candidates includes network_name so users can whitelist
+   or blacklist by IFAC network name.
