Merge ngit external-access PR 79ca68c1 into combined UAT candidate

Preserve current maintenance/session guards, Firewall UI and existing catalogs.
Retain scoped guest access, publishing journeys and local Blossom integration.
Normalize Blossom/router memory units to supported quadlet suffixes.

Validation: 108 dashboard tests, 10 gateway policy tests, strict source catalog
check. Integrated isolated backend qualification remains required before main.
