Cardano Updates

Introduce decoupled liveness and readiness probe endpoints to improve stability and traffic routing in orchestrated environments like Kubernetes.

- Add GET /health for a lightweight HTTP-server-only liveness check.
- Add GET /healthz for node connectivity readiness, backed by a background poller.
- Add configuration for background health check interval.
- Fix nil pointer risk in submit witnesses parsing and style issues.
- Update documentation in README.md.

BREAKING CHANGE: The /healthcheck endpoint has been completely removed and replaced with /health and /healthz. Any external health checks/probes targeting /healthcheck will receive a 404 and must be updated.

The E2E Package.swift declared swift-tools-version 5.7 and a macOS v12
platform, but the SDK root Package.swift requires macOS v14 (raised from
v13 to v14 in 8.0.0, commit 6218165). This mismatch broke
`xcodebuild build-for-testing` for the e2e target:

  error: The package product 'EdgeAgent' requires minimum platform
  version 14.0 for the macOS platform, but this target supports 13.0
  (in target 'e2e-tests' from project 'e2e')

And with the lower swift-tools-version, `.macOS(.v14)` is itself
unavailable (it requires swift-tools 5.9+, which introduced the v14
platform).

Bump swift-tools-version to 5.9 and raise the E2E macOS platform to v14
so the test target builds against the 8.x SDK.
