API docs: Contract build, deployment & invocation guide

[codebestia]

Write contracts/docs/api-deployment-invocation.md — a practical guide for building, deploying, and invoking these three contracts using the actual tooling this repo uses (Soroban CLI commands, contracts/scripts/ if populated, rust-toolchain.toml version, and how the frontend's lib/soroban.ts locates deployed contract IDs).

Acceptance criteria:

• Build and test commands are documented and verified to actually work by running them
• Deployment steps (network selection, identity/funding, deploy command) are documented for at least testnet
• How a deployed contract ID reaches the frontend is documented precisely
