perf: zero JDBC on server thread + HikariCP + parallel shutdown + audit fixes
- Migrate connection pool from manual LinkedBlockingQueue to HikariCP (eliminates isValid() ping on every query visible in Spark profiler) - Move ALL DB writes off server thread: logout uses snapshot+async+latch, shutdown uses snapshot+CompletableFuture.allOf for parallel saves - Pre-read curios/accessories/cosmeticarmor/attachments on background thread during login (4-7 fewer DB queries on main thread per login) - Auto-save interval increased to 5 minutes - Fix pool shutdown ordering: shutdownPool() now runs AFTER all shutdown saves complete (previously could fire before, silently losing all data) - Fix connection leak in executeQuery/executePreparedQuery when prepareStatement throws (leaked connections exhaust HikariCP pool) - Fix duplication bug: saveStorageContents guard used nbt.size()<=1 which blocked legitimately emptied backpacks from saving to DB - Fix stale SaveToFile overwriting logout: check playerLocks.containsKey before writing to prevent stale background task from regressing data - Remove LIMIT 1000 on startup online=0 reset (could leave players stuck) - Add executorService.shutdown() on server stop to prevent JVM hang - Add apply methods (applyCuriosFromData, applyAccessoriesFromData, etc.) to separate entity writes from DB reads for thread-safe restore - Add UUID collectors (collectBackpackUuids, collectSSUuids) and background save methods for snapshot+async logout/shutdown pattern
