Fix(admin-ui): multi warehouse minor fixes (#3540)

**What**
1. Enable the "create location" button in "create stock location" when a field has changed
2. Remove the "successful delete" toast when cancelling stock location creation
3. Properly update available and reserved when editing stock levels for variant
4. invalidate inventoryItemList queryKeys when changing location levels

**Why**
- we had the same bug with form validation when creating location levels as we had when editing them (1)
- when updating location levels, listing inventory items wouldn't show the newly added location levels (4)
- fixing ui bugs (2, 4)
