Title: Image Upscale Service Down - "Failed to get inference reservation: deadline has elapsed" Error

Description:
The image upscale feature has been completely non-functional for at least 5 days. Every attempt to upscale images results in the error: "failed to get inference reservation: deadline has elapsed"

Steps to reproduce:

1. Upload any image

2. Attempt to upscale using the upscale tool

3. Error appears immediately

Expected behavior: Images should upscale successfully to higher resolution

Actual behavior: Timeout error on every attempt

Error message: "failed to get inference reservation: deadline has elapsed"

Duration: 5+ days of complete service failure

Account type: [Pro/Plus/Free - όποιο έχεις]

Impact: Cannot use paid upscale credits, workflow completely blocked

Additional context: This appears to be a backend infrastructure timeout issue. Your changelog shows previous fixes for upscale timeout issues (May 2026: "longer processing timeouts"), but the service is failing again.
