feat: implement sync engine, API handlers, DAPI auth, HTTP client
- Sync engine: BaseSync abstract class + 4 sync modules (users/pricing/uapi/llmage)
- Checkpoint management via sync_state table
- Batch processing with retry and exponential backoff
- Incremental fetch from Sage DB via sqlor
- UPSERT to local cache tables
- API handlers: balance/accounting/users/pricing/health
- Balance: cache lookup + Sage fallback
- Accounting: create with idempotency, query with filters/pagination
- Users: keyword search, org filter
- Pricing: filter by ppid/llmid/type/status
- Health: basic + readiness checks (DB connectivity)
- DAPI auth: middleware + authenticate_request function
- HMAC-SHA256 signature verification
- Timestamp window validation
- Sage downapikey table lookup
- HTTP client: SageHttpClient with aiohttp
- Auto DAPI signature injection
- Connection pooling, retry, timeout
- Router: 12 routes registered
- Module init: load_sageapi() wires everything to ServerEnv
