Standardize ingredient-creation action labels

Equivalent stages of policy, population, simulation, and report creation currently mix labels such as “Add,” “Configure,” and “Create.”

Define and apply one terminology mapping across the pathways and report builder:

• Entry action: “Set up [ingredient]”
• Intermediate action that opens or continues configuration: use the same “Set up” wording unless it performs a distinct operation
• Final persistence action: “Create [ingredient]”
• Existing-record changes: “Save” or “Update,” according to the actual operation

Update relevant tests and stories with the chosen labels.

Search the policy, population, simulation, and report-creation pathways, including the report builder, to find the current action labels. Then update the relevant tests and stories to use the specified distinction between setup, creation, saving, and updating, and verify that all listed flows use consistent wording.
