Fix header wallet balance update after job posting generation

- Update both header wallet balance (a[data-wallet-balance]) and page balance (walletBalance)
- Header balance shows with emoji: 💰 X.XX AED
- Page balance shows without emoji: X.XX AED
- Both elements now update immediately after job posting generation
- Complete wallet balance synchronization across the entire page
