Fix ICP client wiring and missing deployment exports

[johnnyclem]

Motivation

• createICPClient previously required an HttpAgent while callers passed only a config, causing invalid client construction and broken deployment flow.
• validateWasmPath and calculateWasmHash were referenced as standalone imports but only existed as instance methods, preventing reuse by the deployer.
• generateStubCanisterId was exported from the barrel but not implemented, making the deployment index export incorrect.

Description

• Updated ICPClient to accept only an ICPClientConfig and changed createICPClient to createICPClient(config) to align construction across call sites (file: src/deployment/icpClient.ts).
• Added and exported standalone helpers validateWasmPath, calculateWasmHash, and generateStubCanisterId, and refactored the instance methods validateWasmPath and calculateWasmHash to delegate to these helpers (file: src/deployment/icpClient.ts).
• Restored consistency between the deployment barrel and implementation so imports used by deployAgent and getCanisterStatus are valid (affects src/deployment/deployer.ts and src/deployment/index.ts).

Testing

• No automated tests were run on this change.
