fix: resolve MikroTik sensor values and empty SNMP communities
Fixes three critical issues affecting agent-based SNMP polling:

1. MikroTik gauge sensors incorrectly showing 10x values (223°C instead of 22.3°C)
   - Root cause: get_int_value() rejected zero values, causing mtxrGaugeUnit
     to be treated as nil and bypassing divisor logic
   - Fixed: Accept zero values and apply correct divisor=10 for temp/voltage/current/power

2. Empty SNMP community strings sent to agents causing authentication failures
   - Root cause: Devices with source="device" but null community weren't falling
     back to organization/site inheritance
   - Fixed: Enhanced resolve_snmp_community() to fall back to inheritance chain
     even when source="device" but community is empty

3. Continuous MikroTik API commands sent every 60s instead of once per 24h
   - Root cause: MikroTik jobs built on every poll cycle, not just discovery
   - Fixed: Only build MikroTik jobs during discovery phase

Migrations update existing data to fix incorrect divisor values and community
source tracking. Added comprehensive debug logging to diagnose future issues.
