[bugfix] Fix cloud invite code route authentication issue (#5730)

## Summary
- Remove `requiresAuth: true` from cloud-invite-code route to fix
redirect issues in production

## Problem
The `/cloud/code/:code` route had conflicting configurations:
- Route was marked as `requiresAuth: true` in route definition
- But was treated as a public route in the router guard logic
- This caused authentication redirect issues when unauthenticated users
tried to access invite links

## Solution
Removed the `requiresAuth: true` meta property from the
cloud-invite-code route, allowing it to properly function as a public
route that redirects to login with the invite code.

## Test plan
- [x] Access `/cloud/code/TESTCODE` while logged out - should redirect
to login with `inviteCode` query param
- [x] Verify no authentication errors in console
- [x] Confirm invite code is preserved through the redirect flow

Fixes authentication redirect issue for cloud invite links
