* feat(infra): add lightweight meal-order-manager-dev (PLAT-210)
Parameterize the HCP root for seahaven-dev with schedules, PITR, alarms, and Paychex gated off so a second env does not clone production cost or side effects.
* fix(infra): drop prod-only authorizer import so dev can create it (PLAT-210)
The PLAT-102 import is already in meal-order-manager-prod state. A shared import block fails in seahaven-dev because the permission does not exist there.
* fix(iam): allow creating the weekly-menu githubdeploy role in seahaven-dev (PLAT-210)
Prod imported that role. A new account needs CreateRole on tf-managed/githubdeploy-meal-order-manager-weekly-menu.
