Missing subproject build errors in project BOM after changing parent project

[mkne]

Project BOM doesn't contain Parts from sub-projects after moving sub-projects from one project to another and project is therefore not saveable.

To Reproduce

1. Create a Project 2SL with sub-projects Mainboard and Sensorboard
2. Add Parts to the BOMs of Mainboard and Sensorboard
3. Set Associated builds part to the Mainboard and Sensorboard projects
4. Create a second Project 2SL-Archive and save
5. Change the Parent Project of Sensorboard to 2SL-Archive
6. Add an image as file attachment to the Project 2SL-Archive and click save
7. Image can not be saved and screenshot looks similar to the screenshot below

Expected behavior
When assigning a project to a new parent project the BOM of the parent project has to be updated with the parts contained in the sub-project BOM and adding an attachment or saving edits in the parent project are possible.

Server Side

• Part-DB Version: 2.9.0
• PHP Version: 8.4.18
• Database Server: sqlite

Just a comment to my intentions: I realized that my current organization of project prevents using the build project function for the parent project (whole device) as I now have a board with more than one revision. I still want these old revisions in part-db because I might need them for spare parts. So my I idea was to create an Archive Project for every end product (Parent Project) where I can move the old revision projects to. I also want to add additional sub-projects of boards there that do not land in the end product but are needed for development like a special debug adapter board.
