jtricerolph d7898ba897 Add 'use main stack settings' toggle for third-party integration credentials
Each of Newbook, Resos, SambaPOS, SMTP, and Nextcloud now has a checkbox at the
top of its credentials block. When enabled, the app reads auth credentials from
the central stack settings service (SETTINGS_URL + STACK_INTERNAL_SECRET) and
the local auth fields are grayed out. App-specific fields (base path, GL codes,
keywords, sync intervals, etc.) remain editable regardless.

Backend: new use_global_* columns on kitchen_settings, migration, global_settings_service
with apply_global_overrides() for in-memory credential injection, GET /api/settings/global-status
endpoint, and apply_global_overrides() called in test-connection endpoints and FileArchivalService.

"""
Fetch integration credentials from the central stack settings service.
When a kitchen setting has use_global_<slug>=True, the backend reads credentials
from the settings service (SETTINGS_URL) instead of the local kitchen_settings row.
apply_global_overrides() modifies the KitchenSettings object IN MEMORY only — it does
not commit anything to the DB.
