Keep connection list health compact by default

[baggiiiie]

issue

see #1647

root cause

the root cause for this issue is, connection.lastHealth is copied directly to connections.list output, and its schema used the full HealthCheckResult. The existing verbose option controlled only the full OAuth scope string, not health diagnostics.

fix

connections.list now outputs:

• Default or verbose: false: status, identity, and checkedAt only.
• verbose: true: the complete health result, including httpStatus, detail, and responseSample.

Connection detail, create, refresh, and HTTP API behavior remain unchanged. Unit and end-to-end tests cover both compact and verbose responses.

hmm the ci failures seem to be flaky tests? this PR only touches core-tools.ts, the failures shouldn't be caused by the diff

i think cloud2 has flaky test assertion, cloud5 could be some load-dependent bug
