…Dash-Studios#649) - Track hint usage durably, keyed by userId:hintId (deduplicated per user) - Persist records to Redis under hint:usage:... and unique-user sets under hint:users:... - Add getHintUsageAnalytics() aggregating totalUses, uniqueUsers, usesByHint, usesByDifficulty - Mirror Redis state into a fresh service instance so counts survive restarts - Expose GET /ai/hints/analytics endpoint - Add unit tests for dedup, user-scoping, difficulty distribution, and restart durability

Closes #649
Description
In-memory hint counts disappear on restart and cannot support difficulty calibration across instances. This change makes hint usage durable, user-scoped, deduplicated per user, and queryable for analytics.
