Migrate all server modules to use the centralized logger (lib/logger.ts)
instead of raw console calls. Lint warnings reduced from 74 to 25.
Remaining warnings are only no-floating-promises in game engine code.
Files updated: orchestrator.ts, ranked-queue.ts, human-responses.ts,
payments.ts, fight-loop.ts, app.ts, routes/payments.ts
Files suppressed: logger.ts, fight-loop-cli.ts, migrate.ts (legitimate console use)
