/**
 * Confirm Specific Radio Selections Before Submitting (per‑form, configurable)
 *
 * GOAL:
 * - Shows a confirmation dialog when a selected radio value matches configured choices. Prevents
 *   accidental submissions for critical options.
 *
 * CONFIGURATION:
 * - Edit cfg below:
 *   - fieldId: numeric field ID of the radio field (e.g., 3)
 *   - messages: map of radio option value => confirmation message
 *   - applyToFormIds: optional array of form IDs; empty means apply to any form on the page
