Nitpicks

• part table; description is not sortable
• on inv update: discard po changes
• PUI: headers and part table should be links feat(PUI): Make header tabs links to simpilfy new tab behaviour inventree/InvenTree#8779
• PUI: error if no frontend was included

Features

• Add tools in BOM (maybe as a flag) -> no included in BOM price but everything else; should be able to be ordered
• Make parameters lockable (See LD vision)
• User-based settings for trees -> save tree state
