Validate host/target fields (hostname or IP; host allows */** wildcards)

Browse Source 
Backend (utils/hostname_validate.js, enforced in routes/host.js on create/update):
- host: IPv4 or a wildcard pattern whose labels may be normal, "*" (one
  fragment) or "**" (any depth, incl. a bare "**" catch-all) — matching
  Host.lookUp. Lowered Host.host min length to 1 so "**"/"*" pass the model.
- target (ip): IPv4 or a strict hostname, no wildcards.
- Both reject scheme, "/", ":" and whitespace; 422 with per-field keys.

Frontend (val.js) mirrors the rules: host/target validators + hosts.ejs fields
point at them. Unit tests in test/unit/hostname_validate.test.js.
