feat: upgrade vss-client to vss-client-ng 0.4

- Update dependency from vss-client 0.3 to vss-client-ng 0.4
- Adapt to new StorableBuilder API (AAD parameter, key by reference)
- Store data_encryption_key separately in VssClient struct
- Update MSRV to 1.75+ in documentation
- No changes to public FFI API

Note: Data encrypted with vss-client 0.3 is not compatible with this version due to AAD changes in the encryption scheme.
