Beta release v0.2.5.1b7

Short beta update for the Print Farm Manager / Farm Command Center branch.

Highlights

• Reuses the same printer status classification as the main Printers page.
• Prevents stale completed print metadata from showing idle printers as still printing in Farm Command Center / TV Mode.
• Includes recent K2 current-print metadata and filament estimate fixes from feat/pfm.

Notes

• This is a prerelease for testing the feat/pfm workflow.
• Beta updates must be enabled in Printbuddy to see this release in the updater.
• Docker testers should use the matching image tag v0.2.5.1b7 instead of dev if they want this exact beta build.
