ci: Switch to CalVer (YYYY.MM.BUILD) with auto-generated versions

Remove manual semver validation from PR checks. Versions are now
auto-generated on merge to main by counting existing monthly tags.

-# SETUP REQUIRED
-# ==============================================
-# Before this workflow will work:
-#
-# ✅ Add secrets to Gitea repo (Settings → Secrets → Actions):
-#    - DOCKERHUB_USERNAME: manticorum67
-#    - DOCKERHUB_TOKEN: Docker Hub access token
-#    - DISCORD_WEBHOOK_URL: Discord webhook for build notifications
-#
-# ✅ Ensure VERSION file exists in repo root (currently: 2.4.1)
-#
-# ==============================================
-# TROUBLESHOOTING
-# ==============================================
-# Common issues and solutions:
-#
-# 1. VERSION validation failing unexpectedly
-#    - Ensure VERSION file contains only version number (no 'v' prefix)
-#    - Verify version follows semver: MAJOR.MINOR.PATCH
-#
-# 2. Docker Hub push failing
-#    - Verify DOCKERHUB_USERNAME and DOCKERHUB_TOKEN secrets are set
-#    - Check Docker Hub token has push permissions
-#
-# 3. Discord notifications not appearing
-#    - Test webhook URL manually with curl
-#    - Check webhook still exists in Discord channel settings
-#    - Look for HTTP error codes in Actions logs

+### Commands
+```bash
+docker-compose up                          # Start all services
+docker-compose pull && docker-compose up --build  # Pull latest and rebuild
+docker-compose --profile sync up sync-prod # One-time production data sync
+```
+
+### Logs
+- **Container logs**: `docker logs --since 1h sba_db_api`
+- **Log file (in container)**: `/usr/src/app/logs/sba-database.log` (rotating, 8MB, 5 backups)
+- **Health check**: `GET /api/v3/current` (curl built into Dockerfile healthcheck)
+
+### Common Issues
+- 500 errors → check `docker logs sba_db_api`, look for Peewee/PostgreSQL connection errors
+- Stale data → Redis cache; clear with `docker exec sba_redis redis-cli FLUSHDB`
+- DB connection pool exhausted → restart API container (pool: 20 connections, 5min stale timeout)
+- **CI/CD**: Gitea Actions on PR to `main` — builds Docker image, auto-generates CalVer version (`YYYY.MM.BUILD`) on merge
