Implement bonding curve milestone data API for graduation progress

[Chucks1093]

Summary

Expose an endpoint returning the full milestone configuration and current progress for a key's graduated bonding curve so the client can render the progress tracker.

Scope

• GET /keys/:keyId/curve/milestones — all milestones with supply thresholds and price breakpoints
• Current supply and price included in response
• Next milestone computed server-side
• Graduation event flag when final milestone reached
• Data refreshed every 30 seconds via polling cache

Acceptance Criteria

• Milestones returned with correct supply and price values
• Current position reflects live on-chain supply
• Next milestone correctly identified from current position
• Graduation flag set when supply meets final milestone
• Cache updated every 30 seconds

ETA

12 hours

I would love to take this on. My planned approach:

• Verify API response schemas, authentication middleware, and database rollback safety.
