Skyfay/DBackup v2.7.0 on GitHub

Backup Integrity Verification, Storage Explorer Caching, and Multiple Improvements

integrity: Added backup file integrity verification. The Storage Explorer shows SHA-256/MD5 checksums and last verification result per file, with a Verify Now button that runs as a tracked async execution with live progress and cancel support.
integrity: Native checksum verification for S3/R2/Hetzner (SHA-256 via object metadata), Google Drive (MD5 via API), OneDrive (SHA-256 via Graph API), and local filesystem - no download required. Both checksums are stored in .meta.json at upload time.
integrity: Post-upload verification is now opt-in for all storage destinations via system settings (local filesystem always verifies).
integrity: Scheduled integrity checks support two scan modes - Jobs (default, only verifies files linked to backup jobs) and All Files (full storage scan) - plus configurable filters (skip already-passed, max age, max file size). Jobs and storage destinations can individually opt out via a "Skip Verification" toggle.
storage: Storage Explorer file listings are now cached in SQLite for instant repeat visits. Cache is invalidated on backup create, delete, verify, and lock changes.
history: Execution logs can now be copied to the clipboard or downloaded as a .log file directly from the log dialog. Sensitive data (IPs, credentials, connection strings) is automatically redacted before export.

storage: Google Drive, OneDrive, and Dropbox now live-validate their stored OAuth token when the Connection tab is opened, showing an expiry warning with a Re-authorize button instead of a misleading green "authorized" status.

dev: pnpm dev now automatically applies pending Prisma migrations and regenerates the Prisma client on startup.
storage: Storage Explorer cache uses surgical updates - create, delete, lock, and verify each patch only the affected cache entry instead of invalidating the full cache.
storage: A new "Pre-warm Storage Cache" system task (enabled by default, hourly) reconciles caches against remote storage and pre-populates the cache for adapters not yet visited.
storage: Stale cache entries trigger a background reconciliation via adapter.list() to detect files deleted outside DBackup without re-reading sidecars.
storage: Long backup names in the Storage Explorer are truncated with a tooltip showing the full name on hover.
integrity: Manual system task runs auto-redirect to the live execution history when "Auto-redirect on job start" is enabled.
ui: All data tables (Storage, Jobs, Sources, Destinations, Notifications) now support horizontal scrolling when columns overflow.
explorer: Database version history now detects and visually distinguishes downgrades - the change log shows an orange downward arrow for downgrades vs. green upward arrow for upgrades, and downgrade notifications are sent with a distinct "Downgrade" label and warning color.
explorer: Database Explorer table list now supports searching by name and sorting by Name, Type, Rows, or Size via clickable column headers.

tests: Updated unit tests for integrity service, upload step, storage service, and system task service to match the refactored verification interfaces.
tests: Fixed integrity service tests to use destinations scan mode explicitly and added skipVerification field to job service create test.
tests: Added unit tests for VerificationService (all verification code paths), SystemTaskRunner (execution lifecycle), logs/sanitize (credential and IP redaction), and logs/format (log text export). Extended IntegrityService tests to cover the jobs-mode scan path.
