Optional priority flag on partner video uploads

Please add an optional priority parameter to the partner upload API (for example on add_video_by_url). The partner uses it to say how soon PB Vision should start to process a video.

Suggested values, as a target for the start of processing:

• 4h: start within 4 hours

• 8h: start within 8 hours

• 12h: start within 12 hours

If the field is absent, PB Vision uses its current default. Existing integrations do not change. We treat the value as a target, not a guarantee.

Why we need it: partners such as clubs and coaches upload video with their own API key, and the urgency differs by video. A coach who records a lesson wants the analysis before the next lesson. A club that uploads a full day of games for a monthly review can wait. Today, PB Vision cannot tell these two cases apart.

Why it helps PB Vision: you see the real urgency of each video. You can handle urgent videos at peak hours and run the rest when capacity is free. A partner that accepts a 12-hour start gives you more room to schedule.

Items to consider:

• You may want to price faster start times higher, or give a discount for slower ones. We are open to either.

• Show the requested priority and the expected start time in the video status.

• Reject an unknown value with a clear error.

• Let a partner change the priority of a video that has not started yet.
