What’s in this release

- Reliability and auth/coordinator fixes: use of a dedicated session for SeventeenTrack to preserve login cookies, improved ProxmoxVE permissions handling and prevention of migration‑triggered reauthentication, Victron BLE reauth and storage fixes, and improvements to coordinators such as Tibber and Anglian Water to reduce stale data and unexpected reauths.
- Backups, Backblaze B2 and dependencies: bump and fix securetar (including size calculation when encrypting backups), handle BadRequest in Backblaze B2 config flow/setup and improve B2 upload error logging, plus a large set of dependency upgrades and a frontend update (frontend 20260325.7).
Upgrade notes
- No breaking changes are listed in the release notes; review the full GitHub release notes before upgrading and follow your usual upgrade procedure.
