fix: improve agent polling and SNMP testing
Changes: - Fix traffic graph to handle nil interface octets gracefully - Add comprehensive tests for nil octets scenarios - Fix agent polling query to support devices assigned directly to org (left join on sites) - Fix test SNMP connection to inherit credentials from site/org - Refactor agent_channel process_polling_result to reduce nesting (Credo) - Add alias for JobCleanupTask in application.ex (Credo) This fixes crashes when interface stats have nil octets and ensures devices without a site assignment can be polled by agents. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
