fix(dashboard): Load product variant edit page and fix product detail query key (#10029)

**What**
- Fixes Edit Variant form so it properly loads the product variant
- Fixes the query key for product details to prevent the cache from being shared between queries for the same ID but with different params.

Resolves CMRC-685
