fix: apply authLimiter to OTP and password reset routes

[shravya290706]

Summary

This PR applies authLimiter to OTP and password reset endpoints that were previously protected only by dashboardLimiter.

Changes Made

• Added authLimiter to:

  • /send-otp
  • /verify-otp
  • /forgot-password
  • /reset-password

Why

These endpoints were inheriting dashboardLimiter (1000 requests / 15 min), making them vulnerable to:

• OTP brute-force attempts
• OTP email spam
• Password reset abuse
• User enumeration attacks

Applying authLimiter aligns them with the same protection already used for login and registration endpoints.

Fixes #246

Summary by CodeRabbit

• Bug Fixes
  • Applied rate limiting to sensitive authentication endpoints including OTP sending and verification, password recovery requests, and password reset operations to prevent abuse and enhance system stability and security against unauthorized access attempts.

📝 Walkthrough

Walkthrough

The PR applies the strict authLimiter middleware to four authentication endpoints—/send-otp, /verify-otp, /forgot-password, and /reset-password—preventing them from inheriting the permissive global dashboardLimiter. This limits these sensitive endpoints to 10 requests per 15 minutes instead of 1000, closing brute-force and enumeration attack vectors.

Changes

Auth endpoint rate limiting

Layer / File(s)	Summary
Auth endpoint rate limiting apps/dashboard-api/src/routes/auth.js	The /send-otp, /verify-otp, /forgot-password, and /reset-password route definitions are updated to explicitly chain authLimiter middleware, protecting these sensitive endpoints from brute-force and enumeration attacks by enforcing the strict 10-request-per-15-minute limit.

🐰 A rabbit hops to guard the gate,
With timers firm to rate-limit fate,
Ten tries per fifteen—a fortress wall,
No brute-force beast shall breach at all! 🔒

In `@apps/dashboard-api/src/routes/auth.js`:
- Around line 43-47: The four routes using authLimiter (router.post('/send-otp',
authLimiter, sendOtp); router.post('/verify-otp', authLimiter, verifyOtp);
router.post('/forgot-password', authLimiter, forgotPassword);
router.post('/reset-password', authLimiter, resetPassword);) are currently
registered after router.use(dashboardLimiter) and thus inherit dashboardLimiter
in addition to authLimiter; move these four router.post registrations up so they
are placed alongside the existing /register and /login routes (before the
router.use(dashboardLimiter) call) so only authLimiter is applied and the
dashboardLimiter state is not unnecessarily tracked for these endpoints.
