The RC3 memory bound for PBS backup polling summarized any group with
more than 8 snapshots into a single synthesized entry built from group
metadata. A synthesized entry has no verification, size, file, or
per-snapshot time data, so most real deployments saw every backup as
Unverified with no size, PBS files not listed, and a backup timeline
collapsed onto the latest backup day.
Keep the issue #1524 memory bounds but derive them from real data:
always fetch snapshots for stale groups, retain the newest bounded set
per group (limit raised from 8 to 100 to cover real keep policies), and
keep the newest-first global live-state cap. Remove the synthesized
group placeholder path entirely and update the monitoring subsystem
contract and tests to pin real-snapshot bounding.

- persist scoped workloads status filters across platform navigation
- derive host memory pressure from available memory
- reapply system settings after every monitor reload path
- bound PBS backup snapshot polling workers during large backup scans
TestMonitorPollGuestSnapshots_RefreshesStaleCanonicalStoreForClusterGuest
passed context.Background() to pollGuestSnapshots, which creates an
internal 60s snapshot timeout. The backupStorageTimeoutSnapshotClient
mock blocks GetStorage until context cancellation, so the test wasted
60s waiting for the timeout to expire. Pass a 200ms deadline context
so pollGuestSnapshots caps its budget down — test now runs in 0.2s
instead of 60s and no longer times out under -race.
