Fixes "No active session found" error when adjusting game settings
before starting a game in arcade rooms.
**Problem:**
- Sessions were only created on START_GAME move
- SET_CONFIG moves require an active session in setup phase
- Users couldn't adjust settings until after starting game
**Solution:**
- Create session in setup phase when user joins room (if none exists)
- Initialize with room's game config from database
- Allows SET_CONFIG moves before game starts
**Changes:**
- socket-server.ts:72-100 - Auto-create session on join-arcade-session
- RoomMemoryPairsProvider.tsx:4 - Remove unused import
- nas-deployment/docker-compose.yaml:15 - Fix DB volume mount path
**Related:**
- Also fixes database persistence by correcting volume mount from
./data:/app/data to ./data:/app/apps/web/data

**Problem:**
- player-ownership.ts imported drizzle-orm and @/db at top level
- When RoomMemoryPairsProvider imported client-safe utilities, Webpack bundled ALL imports including database code
- This caused hydration error: "The 'original' argument must be of type Function"
- Node.js util.promisify was being called in browser context
**Solution:**
1. Created player-ownership.client.ts with ONLY client-safe utilities
- No database imports
- Safe to import from 'use client' components
- Contains: buildPlayerOwnershipFromRoomData(), buildPlayerMetadata(), helper functions
2. Updated player-ownership.ts to re-export client utilities and add server-only functions
- Re-exports everything from .client.ts
- Adds buildPlayerOwnershipMap() (async, database-backed)
- Safe to import from server components/API routes
3. Updated RoomMemoryPairsProvider to import from .client.ts
**Result:**
- No more hydration errors on /arcade/room
- Client bundle doesn't include database code
- Server code can still use both client and server utilities
