Expose the ssdp_scanner.probe_timeout option (default 2s, mirroring the
mDNS scanner) in the sample config and the NixOS service module.

Introduce a second discovery module that passively listens for mDNS
multicast announcements (224.0.0.251:5353) and feeds discovered devices
into the existing devices/events/notifications pipeline, running in its
own task alongside the ARP scanner.
Since mDNS carries an IP and hostname but no MAC (the device key), the
module resolves IP->MAC via the OS ARP cache with a targeted ARP-probe
fallback. The advertised hostname is stored in a new optional `name`
column on devices (blank for ARP-only devices); the single `update`
writes `name` only when set so ARP rescans never clobber it. Device
names are included in event/notification messages.
Adds a GET /api/mdns_scanner/status endpoint (is_listening, devices_seen,
last_device_seen_seconds_ago) wired into OpenAPI, an optional
[mdns_scanner] config section, and the corresponding Nix module option.
Also aligns the Nix module's stale `timings` section with the current
`arp_scanner` schema.

If no interface is set in the config, the ARP scanner now picks the
first non-loopback, up, IPv4-enabled interface automatically. The
setting is optional in the TOML config, sample config, and Nix module.

Adds the retention.window option to the NixOS module and documents it
in the README alongside a new Storage considerations section covering
per-network-size estimates and guidance on tuning scan timings and the
retention window to meet storage requirements.
