Add Zcash wallet connection via Zodl to the web3 connect wallet UI, including QR code generation using UFVK and seed fingerprint. Also add nix flake with devShell and build scripts.
Add RUSTUP_TOOLCHAIN export to fix toolchain resolution, production build variants, and scripts for firmware-maker/checker workflow.

Explanation
Since zcash is already supported on Keystone Nexus and on the multicoin firmware, I thought it made sense to add zodl support to the multicoin firmware as well.
In addition, I added nix flake support to make developing this firmware easier for a first-time developer. Simply running
nix develop(of course having nix installed first) will drop you into an isolated dev environment that is able to compile everything and generate firmware.The tests appear to be broken however, they currently fail to compile on the specified version of rust that this project uses. I decided not to fix this for now to keep the scope limited to the two features above. The tests seem to be always broken for this version of rust (released on 2025-07-01 for baremetal architecture thumbv7em-none-eabihf).
