Empty inbound tokens were gated on the WebUI page hostname / client IP,
so a remote panel visit blocked clearing the token even when the
listener was 127.0.0.1. Trust the bind host as well: loopback listeners
are not reachable from outside, while 0.0.0.0 still requires a local
WebUI session.
Use safer defaults for newly created service endpoints and guide operators toward suitable access credentials without disrupting existing deployments.
Apply the same policy at the save boundary, retain deliberate local-only setups and external client compatibility, and add regression coverage for editing, recovery, and trusted access paths.
