docs: fix stale Docker paths and park region counts

Update /app/data → /app/backend/data across all docs to match the
volume mount fix from 3c91d9a. Add missing TZ env var to the web
container snippet in OPERATIONS.md. Correct Midwest (6→7) and
West & International (6→5) park counts in ARCHITECTURE.md.

 ### What to Back Up

 ### Backup Methods
 
 **Method 1: Copy from the container**
 ```bash
-docker compose cp backend:/app/data/parks.db ./backup/parks.db
-docker compose cp backend:/app/data/parks.db-wal ./backup/parks.db-wal 2>/dev/null
-docker compose cp backend:/app/data/parks.db-shm ./backup/parks.db-shm 2>/dev/null

+docker compose cp backend:/app/backend/data/parks.db-shm ./backup/parks.db-shm 2>/dev/null
 ```
 
 **Method 2: Mount the volume to the host**
 Add a bind mount in `docker-compose.yml`:
 ```yaml
 volumes:
-  - ./data:/app/data
+  - ./data:/app/backend/data
 ```
