 * Tests for GitHub issue #7802: volume mappings from repo content in Preview Deployments.

 * Bind mount volumes use a per-volume `is_preview_suffix_enabled` setting to control
 * whether the -pr-N suffix is applied during preview deployments.
 * When enabled (default), the suffix is applied for data isolation.
 * When disabled, the volume path is shared with the main deployment.
 * Named Docker volumes also respect this setting.
