- M17: default SNMPv3 auth protocol on the four SNMP executors
(interface/storage/processor/sensor) is now SHA-256 instead of MD5.
Devices that explicitly set MD5 still use it; only the fallback for
unconfigured devices changes.
- M23: permissions check now logs a warning when an org's memberships
aren't preloaded so a silent denial is visible at the call site
instead of looking identical to a real authz failure.
- L9: extracted the duplicated should_sync?/1 logic from gaiia, sonar,
splynx, visp, and netbox sync workers into
Towerops.Integrations.due_for_sync?/2. Each worker now passes its
own default interval (10 or 30 minutes) to a single shared helper.
Tests updated to cover the helper directly.
