Adds rate_limit(name, max_hits=, window_seconds=) as a factory for FastAPI
dependencies, generalizing the auth_rate_limit pattern for future endpoints
(chat send, message report) without touching auth_rate_limit's own behavior.
Reuses SlidingWindowLimiter for counting and the existing 429 + Retry-After
response, and respects RATE_LIMIT_ENABLED the same way auth_rate_limit does.
reset_all() now clears every registered limiter (auth's plus any named ones),
so the conftest autouse fixture keeps working for sibling tasks automatically.

Every checkpoint smoke test registers users against one backend from one
client IP, so the per-IP auth limit tripped mid-suite (main_menu_full_flow
-> 2/12). Add RATE_LIMIT_ENABLED (default true); run_checkpoint_tests.py
sets it false for its backend. test_rate_limit.py forces it on in-fixture
so the limiter is still really tested.

app/rate_limit.py: an in-process sliding-window limiter (single-worker
backend, so no Redis needed -- flagged for if that changes). /register and
/login are capped at 10 attempts / minute / client IP (X-Forwarded-For
aware), returning 429 + Retry-After past that. Blunts credential
brute-force, which the backend had no protection against.
- conftest.py resets the limiter between tests (every TestClient request
looks like one IP).
- tests/test_rate_limit.py: threshold, shared bucket, per-key window. 77 passed.
CORS reviewed while here: already an explicit origin allowlist
(settings.CORS_ORIGINS), not "*" -- and the Godot client isn't a browser
so it doesn't apply there anyway. Left as-is.
