fix: remove legacy SQLite compatibility code (#122 )

Closes #122

Both prod and dev environments use PostgreSQL. Removes all SQLite
compatibility code that was never exercised in practice.

Changes:
- db_engine.py: replace SQLite/PostgreSQL branching with direct
  PooledPostgresqlDatabase init; remove DATABASE_TYPE, SKIP_TABLE_CREATION,
  all db.create_tables() calls, and commented-out SQLite scout_db code
- db_helpers.py: remove DATABASE_TYPE var and SQLite on_conflict_replace
  branch from upsert_many(); PostgreSQL ON CONFLICT is now the only path
- players.py: update stale comment
- tests/conftest.py: remove DATABASE_TYPE env var (no longer needed);
  keep POSTGRES_PASSWORD dummy for instantiation
- CLAUDE.md: update SQLite references to PostgreSQL

Note: unit tests in test_evolution_seed.py and test_season_stats_model.py
use SqliteDatabase(':memory:') for test isolation — this is legitimate test
infrastructure, not production SQLite compatibility code.

Paper Dynasty Database API

FastAPI backend for baseball card game data. Peewee ORM with PostgreSQL.

Commands

uvicorn app.main:app --reload --host 0.0.0.0 --port 8000  # Dev server
python main.py                                              # Alt start
python db_migrations.py                                     # Run migrations
docker build -t paper-dynasty-db .                          # Build image

Architecture

Routers: Domain-based in app/routers_v2/ (cards, players, teams, packs, stats, gauntlets, scouting)
ORM: Peewee with PostgreSQL (pd_master database via PooledPostgresqlDatabase)
Card images: Playwright/Chromium renders HTML templates → screenshots (see routers_v2/players.py)
Logging: Rotating files in logs/database/{date}.log

Key Constants

LIVE_CARDSET_ID: 24 (current active cardset, in db_engine.py)
ranked_cardsets: Legal cardsets for ranked play
CARDSETS: Configuration for game modes and card availability

Environments & Troubleshooting

	Dev	Prod
URL	pddev.manticorum.com	pd.manticorum.com
Host	`ssh pd-database`	`ssh akamai` → `/root/container-data/paper-dynasty`
API container	`dev_pd_database`	`pd_api`
PostgreSQL	`pd_postgres` (port 5432)	`pd_postgres`
Adminer	port 8081	—
API port	816	815
Image	`manticorum67/paper-dynasty-database`	`manticorum67/paper-dynasty-database`

Logs

Container logs: docker logs --since 1h pd_api
Log file (in container): logs/database/YYYY-MM-DD.log (date-stamped daily, no rotation)
API docs: /api/docs and /api/redoc

Key Env Vars

API_TOKEN, LOG_LEVEL, POSTGRES_HOST, POSTGRES_DB, POSTGRES_USER, POSTGRES_PASSWORD

Common Issues

502 Bad Gateway → API container crashed; check docker logs pd_api
Card image generation failures → Playwright/Chromium issue; check for missing dependencies
DB connection errors → verify POSTGRES_HOST points to correct container name
CI/CD: Gitea Actions on PR to main — builds Docker image, auto-generates CalVer version (YYYY.MM.BUILD) on merge

Release Workflow

Create feature/fix branches off next-release (e.g., fix/card-pricing)
When done, merge the branch into next-release — this is the staging branch where changes accumulate
When ready to release, open a PR from next-release → main
CI builds Docker image on PR; CalVer tag is created on merge
Deploy the new image to production

Important

Docker image installs only Playwright Chromium (not all browsers) to optimize size
Teams have dynamic card pricing based on market activity
Supports both human players and AI teams
Gauntlet events use special reward structures and card pools
