Major refactor of backup and storage paths: - Per-drive restic repos at <drive>/backups/primary/restic/ - Per-app DB dumps at <drive>/backups/primary/<app>/db-dumps/ - Remove global BackupDir, DBDumpDir, ResticRepo config fields - Add SystemDataPath config (fallback for apps without HDD) - New backup/paths.go with pure path computation helpers - Add GetStackHDDPath to StackDataProvider interface - Restic methods now accept repoPath as parameter - Cross-drive backup uses new secondary path structure - Rename storage/ to appdata/ in scripts and compose templates - Update protected HDD paths (storage → appdata + backups) - Simplify backup UI (remove global path displays) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
