perf(edit-pages) : reduce blocking API calls on edit pages

- Remove redundant getCustomFieldValuesByEntity() calls (use entity response)
- Remove redundant refreshDocuments() from onMounted (docs already in entity)
- Make loadHistory() non-blocking (fire-and-forget)
- Defer bulk catalog loads on component edit (pieces/products/composants)
- Use pieceTypes cache instead of separate getModelType() call on piece edit
- Try embedded typeProduct from entity response on product edit
