fix(mdns-scanner): browser par type au lieu d'une recherche globale

Browse Source 
bonjour-service exige un `type` dans BrowserConfig ; il n'existe pas
d'option pour écouter "tous les services". Le scanner instancie
maintenant un browser par type mDNS courant en homelab (http, ssh,
smb, airplay, googlecast, homekit, ipp, etc.) et agrège les
annonces par IP via une fonction `ingest` partagée.
