Bug Fixes

Fix PVE node duplication — UpdateNodesForInstance now filters out nodes belonging to the current instance before merging, matching the UpdateVMsForInstance pattern. Previously, stale node entries could persist when node IDs changed between poll cycles (cluster vs standalone, different endpoint URLs), causing duplicates. (#1214, #1192, #1217)
Fix alert hostname scrambling — Active alerts are now sorted by node name and alert ID before being sent to the frontend, ensuring stable ordering across poll cycles. Previously, Go's random map iteration caused hostname labels to shuffle every 5 seconds. (#1218)
Fix ntfy resolved webhook formatting — Resolved alert webhooks now send proper ntfy-formatted notifications with a plain-text body and appropriate headers (Title, Priority, Tags) instead of raw JSON. (#1213)
Fix Docker "Update All" button ignoring hide setting — The "Update All" button in the Docker filter bar now respects the "Hide Docker update actions" system setting, matching the behavior already applied to individual container update badges. (#1219)
Fix version link 404s — Update banner release links now correctly include the v prefix in GitHub tag URLs (e.g., /tag/v5.1.5 instead of /tag/5.1.5). (#1195)
Reduce disk detection warning spam — The "VM reports disk usage significantly larger than allocated disk" message has been reduced from Warn to Debug level, eliminating noisy logs for environments with pass-through disks, NFS mounts, or ZFS datasets. (#1216)
