cleanup: remove unused imports, merge duplicates, drop stale comment

- Remove unused _ml_logging_enabled import from routes/deepseek.py
- Remove dead _ml_logging_enabled top-level import and
  _ml_logging_enabled_local alias from routes/ml.py (endpoints already
  use the module-path form via import services.logging)
- Merge duplicate from services.precon_service imports in routes/precon.py
- Merge duplicate from models.requests imports in routes/deckgen.py
- Remove redundant inline comment in routes/precon.py

-/**
- * PolicyClient — Phase 2 bridge between Forge decision points and the
- * Python policy server for live online training.
- *
- * This class extends the existing LearnedPolicy/PolicyServerClient
- * infrastructure with two key Phase 2 capabilities:
- *
- * 1. Calls the new /api/policy/decide endpoint (purpose-built for live
- *    IPC with richer state including all zones, stack, and priority)
- *    instead of the batch-oriented /api/ml/predict.
- *
- * 2. Collects (state, action, reward) tuples in real-time during live
- *    Forge games and flushes them to the policy server for online PPO
- *    updates via POST /api/policy/collect.
- *
- * Falls back to ForgeBuiltinPolicy heuristics if the policy server
- * is unreachable or returns an error.
- *
- * Usage:
- *   PolicyClient client = new PolicyClient("http://localhost:8080");
- *   if (client.connect()) {
- *       // At each Forge decision point:
- *       String action = client.decide(fullGameState);
- *       // After game ends:
- *       client.submitReward(gameId, reward);
- *       client.flushCollectedTuples();
- *   }
- *
- * Refs: Issue #83 Phase 2.1
