refactor: hardcode API IDs and coaster lists, remove Playwright discovery

Embed Six Flags API IDs directly in the park registry and snapshot
coaster lists from park-meta.json into a TypeScript module. This
eliminates the Playwright-based discovery script, RCDB scraper, and
runtime dependency on park-meta.json — preparing for the backend
API transition.

- Add apiId field to Park type and all 24 park entries
- Create lib/coaster-data.ts with hardcoded coaster lists
- Update page components to use park.apiId and new getCoasterSet()
- Remove scripts/discover.ts, lib/scrapers/rcdb.ts, lib/park-meta.ts
- Remove data/park-meta.json from shared volume
- Remove playwright devDependency and discover npm script
- Simplify scripts/scrape.ts (no RCDB, no discovery checks)
