fix(admin): fix refund dialog amount for REFUND_REQUESTED, improve button styles

- Don't treat refund_amount as "already refunded" in REFUND_REQUESTED status
  (it's the requested amount, not actually refunded)
- Pre-fill refund amount with user's requested amount
- Show "already refunded" only for PARTIALLY_REFUNDED/REFUNDED orders
- Change action buttons from stacked icon+text to compact inline style
