fix: remove redundant DDL from sync.ts and validate DATABASE_URL

The DDL block in sync.ts was a "safety net" but caused misleading
password auth errors when Coolify's scheduled task ran without
DATABASE_URL injected — the fallback `wc:wc` password was wrong.

- Drop the silent `?? 'postgres://wc:wc@...'` fallback; exit with a
  clear message if DATABASE_URL is missing so the root cause is obvious
- Remove the 90-line CREATE TABLE IF NOT EXISTS block — seed.ts runs
  before the server starts and guarantees all tables exist
