fix: update legacy tests for new AgentCore dual transport architecture

- Update test_redmine_handler.py mock targets from 'redmine' to 'redmine_tools.client'
- Fix async mocking in test_agentcore_integration.py using AsyncMock
- Update test_integration.py imports to use new redmine_tools module
- All 62 unit tests now passing, validates shared RedmineTools works correctly
