refactor: add centralized Zod validators for all API inputs

Create server/src/lib/validators.ts with reusable schemas for all API inputs (auth, fights, bets, payments, tournaments, queue, docs). Import and use in all route handlers, replacing inline validation. Add formatZodError helper for user-friendly error messages. 77 test cases in validators.test.ts cover valid, invalid, boundary, and attack inputs (SQL injection, XSS, prototype pollution).
