feat(dashboard,medusa,ui): Manual gift cards + cleanup (#6380)

**Dashboard**
- Adds different views for managing manual/custom gift cards (not associated with a product gift card).
- Cleans up several table implementations to use new DataTable component.
- Minor cleanup of translation file.

**Medusa**
- Adds missing query params for list endpoints in the following admin domains: /customers, /customer-groups, /collections, and /gift-cards.

**UI**
- Adds new sizes for Badge component.

**Note for review**
Since this PR contains updates to the translation keys, it touches a lot of files. For the review the parts that are relevant are: the /gift-cards domain of admin, the table overview of collections, customers, and customer groups. And the changes to the list endpoints in the core.
