The family gate (decisions 63/64, R-780): family members with their own logins, a permanent forwardAuth door per family app, anchored exceptions, min_controller

- internal/family: the family list (bcrypt, generated 4x4 passwords shown once) + 30-day sessions in family.json
  (0600, atomic); a reset (generation), a removal or a logout ends sessions at the next request.
- internal/stacks/family_gate.go: family_gate / family_gate_except / min_controller in .felhom.yml; the door is written
  BEFORE the first start (install and a removed app's restore), a life record in app.yaml, reconciled by the gate loop;
  priority below the install hold, setup gate and sign-up block; every exception anchored ^/prefix(/|$) (finding F1).
- internal/web/family_gate.go: forwardAuth /__felhom_gate/family (app cookie felhom_famgate, host-only, names a store
  session); /__family/start|login|logout on the dashboard host (session cookie felhom_family, Path=/__family);
  sign-in counted per visitor (clientIP) AND per name, short windows; the household's dashboard session vouches.
  RequireAuth never reads a family cookie. The "Család" card on the security page: add / new password / remove.
