Fix bundled workflow activation + add connection error logging

1. Bundled workflow packages now publish version 1 and set IsActive=true
   after stage creation, so workflows like Content Approval are usable
   immediately — fixes "workflow is not active" test failure.

2. Add error logging to ListConnections handler to diagnose the 500
   error in sdk/connections tests (query and schema look correct but
   the error was being swallowed).

3. Separate "Run All" button text from suite count label.
