🔧 chore(mock.rs): remove unused imports and types

🔧 chore(tests.rs): remove unused Preservation variant
In the `mock.rs` file of the `afloat` pallet, the `UncheckedExtrinsic` type is no longer used, so it has been removed. This improves code readability and reduces unnecessary code.

In the `tests.rs` file of the `fund-admin` pallet, the `Preservation::Protect` variant is no longer used, so it has been removed. This simplifies the code and removes unnecessary options.

In the `mock.rs` file of the `gated-marketplace` pallet, unused imports and types (`RawOrigin`, `Lookup`, `AccountId`, `AccountId32`, `ApplyExtrinsicResult`, `MultiSignature`, `Percent`, `TransactionSource`, `TransactionValidity`, `BlockT`, `IdentifyAccount`, `Verify`, `NumberFor`, `AccountIdLookup`, `impl_opaque_keys`, `
