fix: upgrade uniffI to 0.28.3 and resolve iOS framework conflicts

- Upgrade uniffi from 0.25.3 to 0.28.3 to match bitkit-core
- Use unique header folder VssRustClientFfiFFI to prevent module conflicts
- Fix RustBuffer type incompatibility (int32_t -> uint64_t)
- Update XCFramework build to reference unique header paths
- Updates bindings
- Bumps version to 0.3.1

Resolves build conflicts when using vss-rust-client-ffi alongside bitkit-core in iOS projects.
