fix: Runtime tab respects selected environment

- Add environment parameter to AgentEventsController, AgentEventService,
  and ClickHouseAgentEventRepository (filters agent_events by environment)
- Wire selectedEnv to useAgents and useAgentEvents in both AgentHealth
  and AgentInstance pages
- Wire selectedEnv to useStatsTimeseries in AgentInstance
