  title: Update Function App Settings and Confirm Them
  summary: Read the current app settings, write a merged set, and list them back to confirm.
  description: >-
    A safe configuration-update flow for a function app's application settings.
    The workflow first reads the current app settings via the list action, then
    writes the caller-supplied settings as a full StringDictionary replacement,
    and finally lists the settings again to confirm the new values are in place.
    Because the settings PUT is a full replacement, the initial read gives the
    caller the prior values to merge against. Every step spells out its ARM
    request inline — including the required api-version query parameter and the
    {properties:{...}} StringDictionary envelope — so the flow can be read and
    executed without opening the underlying OpenAPI description. All requests are
    authorized with the azure_auth OAuth2 bearer token carried by the Azure
    Resource Manager endpoint.
