Deploy contract to Stellar testnet and publish the contract ID

[grantfox-oss]

Suggested area: Rust, TypeScript, Deployment

Summary

The contract exists in contracts/anonvote/src/lib.rs and the deploy
steps are documented in the README but the contract has never actually
been deployed. There is no contract ID recorded anywhere in the repo.
sorobanService.ts references a SOROBAN_CONTRACT_ID environment
variable that has no default value and no working testnet ID to test
against. Any contributor trying to wire sorobanService.ts into core
hits a blank env var immediately.

Scope

• Build the contract WASM — cargo build --target wasm32-unknown-unknown --release
  and confirm it compiles cleanly with no warnings
• Deploy to Stellar testnet using the stellar contract deploy command
  documented in the README
• Run initialize with an AnonVote testnet admin public key
• Record the deployed contract ID in a DEPLOYMENTS.md file at the repo
  root — include network, contract ID, admin address, and deploy date
• Add the testnet contract ID as the default value in service/.env.example
  so contributors can run sorobanService.ts against a real deployed
  contract without manual setup
• Confirm cargo test passes against the deployed contract ID

Relevant files

• contracts/anonvote/src/lib.rs
• service/sorobanService.ts
• README.md

Acceptance Criteria

• Contract WASM builds cleanly with no warnings
• Contract deployed and initialized on Stellar testnet
• Contract ID recorded in DEPLOYMENTS.md with network, admin
  address, and deploy date
• service/.env.example contains the testnet contract ID as a default
• cargo test passes against the deployed instance
• README deploy steps verified to work exactly as written — update
  any step that does not

Out of scope

• Mainnet deployment
• Changes to contract logic or function signatures
