feat(projects): select parent projects for app deployments

[bestony]

Summary

• Add a shared parent-project selector to official/custom one-click and Docker Compose setup flows.
• Preserve root selection and clear behavior, including the empty-project state required by one-click and Compose.
• Carry parentProjectId and Compose group projectName through the deployment URL and API request.
• Validate and normalize multi-service Compose project names and block deployment when project loading fails.

Same comment as the backend PR. The previous version was a lot more concise. Please prefer that approach.

Also, let's use the existing key/value pair that we're sending to the backend, rather than introducing a new method in the ApiManager.
