Description

This PR migrates the mobile app https://github.com/moven0831/zkID-mobile-wallet-poc to https://github.com/privacy-ethereum/zkID.

Some critical changes listed as below:

• Replace hardcoded asset path with configurable one for ecdsa-spartan2 implementation (519e4de)
• New FFI layer using Mopro to generate Flutter bindings from Rust crates (48afc3d)
• Add Flutter implementation for both Android and iOS apps (42ac820)
• Refactor docs with new mobile benchmarks (664ef1e and c285404)
