* fix(plugin): remove Min Volume Age field from vacuum plugin worker config
The min_volume_age_seconds setting is not needed as a user-configurable
field in the plugin worker form. The detection logic continues to use
the hardcoded default from NewDefaultConfig().
* fix(plugin): disable volume age filtering in plugin worker detection
Set MinVolumeAgeSeconds to 0 in deriveVacuumConfig so the plugin worker
does not filter out volumes by age during detection.
* fix(plugin): remove all volume age filtering from plugin worker detection
Remove age-related fields from detection trace messages, activity
reports, and per-volume diagnostics. The plugin worker now only
filters by garbage threshold.
