Subject: [PATCH] Add AgentLive.Index edge case tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Added 4 tests covering previously untested scenarios:
- Agent with warning status (2-5 minutes offline)
- Agent with offline status (>5 minutes offline)
- Last seen time formatting (hours and days)

Coverage increased from 80% to near 100%.
