refactor(integration): migrate connectors tests to iggy_harness proc …

…macro (#2667)

Eliminates boilerplate in connector tests by leveraging the same
proc macro infrastructure used for MCP tests. Connector-specific
fixtures (postgres, wiremock, random) moved to tests/ since
they're not part of core harness.

MCP and connectors runtime are now owned by ServerHandle rather
than TestHarness, enabling per-node dependent binaries in cluster
setups.

Also switches test output capture from env_logger to
tracing-subscriber for consistency with server logging.
