## PR-Codex overview
This PR focuses on refining the validation logic for platform fees and royalties in the settings components by removing default values and error handling that were previously in place. This aims to enhance clarity and enforce valid user input.

### Detailed summary
- Removed default values for `platform_fee_basis_points` and `platform_fee_recipient` in `platform-fees.tsx`.
- Removed error handling for invalid `platform_fee_basis_points` and `platform_fee_recipient` in `platform-fees.tsx`.
- Removed default values for `seller_fee_basis_points` and `fee_recipient` in `royalties.tsx`.
- Removed error handling for invalid `seller_fee_basis_points` and `fee_recipient` in `royalties.tsx`.
