feat: skip license page for cloud billing users (#41102)

## Description

This PR enhances the signup success flow to automatically skip the
license page when cloud billing is enabled, providing a smoother
onboarding experience for cloud users.

## Key Changes

### 🚀 New Features
- Added cloud billing detection using `useIsCloudBillingEnabled()` hook
- Implemented automatic license page skipping for cloud billing users
- Enhanced redirect logic with proper async/await handling

### 🔧 Improvements
- Added redirect state management to prevent race conditions
- Improved error handling in redirect flow with try-catch blocks
- Extracted redirect conditions into `shouldAutoRedirect` variable for
better readability
- Added redirect protection to prevent multiple simultaneous redirects

### 🛠️ Technical Details
- Added `isMultiOrgEnabled` flag to signup redirect parameters
- Made `redirectUsingQueryParam` and `onGetStarted` functions async
- Implemented `isRedirecting` state to track redirect status
- Added proper dependency management in useEffect and useCallback hooks

## Impact

- **Cloud billing users** will now bypass the license page automatically
- **Improved UX** with more robust redirect handling and loading states
- **Better performance** by preventing unnecessary redirect attempts
- **Enhanced reliability** with proper error handling and state
management
