Pull request overview

Adds an initial end-to-end (integration) test suite that exercises application lifecycles (Authority + PRT), plus supporting CLI/JSON-RPC API refactors and CI/docker plumbing to run the suite in GitHub Actions.

Changes:

• Introduces endtoendtests-tagged Go integration tests (echo, reject/exception, PRT, multi-app isolation) and helper utilities.
• Refactors JSON-RPC request/response envelopes and decoded input/output types into internal/jsonrpc/api, and extends CLI commands with --json outputs needed by tests.
• Adds Docker Compose + CI workflow updates to build/pull “tester/devnet” images and run integration tests in CI.
