Tests: migrate remaining YAML integration tests to Go runner (PLT-738)

[amir-deris]

Summary

• Wires up the two remaining YAML test files (major_upgrade_test.yaml, minor_upgrade_test.yaml) as TestUpgradeMajor / TestUpgradeMinor in runner_test.go
• Splits TestWasmModule → TestWasmModuleCore + TestWasmModuleEmergencyWithdraw (CI re-deploys the timelocked token contract between them; the withdraw test exhausts state the emergency-withdraw test depends on)
• Splits TestSeiDB → TestSeiDBFlatKV + TestSeiDBStateStore (they run in separate CI matrix jobs)
• Replaces every python3 integration_test/scripts/runner.py call in integration-test.yml with the equivalent go test -tags yaml_integration command, including the shared startup verify step
• Removes actions/setup-python and pip3 install pyyaml from the CI job steps
• Updates upgrade_module/scripts/launch_cluster.sh (local cluster helper) to use the Go runner
• Deletes integration_test/scripts/runner.py

Test plan

• CI matrix passes end-to-end (all matrix jobs use the Go runner now)
• Upgrade module jobs (Upgrade Module (Major/Minor) and their Autobahn variants) exercise the new TestUpgradeMajor / TestUpgradeMinor functions
• Wasm module job redeploys contract between TestWasmModuleCore and TestWasmModuleEmergencyWithdraw
• No python3 or pyyaml references remain in CI workflow

PR Summary

Medium Risk
Changes how all Docker integration matrix jobs execute YAML suites; any behavioral gap between the deleted Python runner and the Go driver would surface as CI failures rather than affecting production code.

Overview
Completes the YAML integration test migration by removing the Python integration_test/scripts/runner.py driver and running every former runner.py invocation through go test -tags yaml_integration on ./integration_test/runner/....

CI (integration-test.yml) matrix scripts and the shared startup check now call named Go tests (e.g. TestWasmModuleCore, TestUpgradeMajor, TestSeiDBFlatKV) instead of per-file Python commands. Python setup (actions/setup-python, pip3 install pyyaml) is dropped from the job.

runner_test.go adds or reshapes entrypoints so matrix jobs match old script boundaries: Wasm split into core vs emergency withdraw (with redeploy between them in CI), SeiDB split into FlatKV vs state store, new TestUpgradeMajor / TestUpgradeMinor, and TestAutobahnBankModule (only send_funds_test.yaml because Autobahn hangs on -b block cases).

launch_cluster.sh uses TestStartup via Go test instead of Python for local upgrade cluster bring-up.
