Summary

• Auto-open Payment Requests modal when a new payment request is received
• On mobile, automatically switch to wallet tab when payment request arrives
• Truncate long nametags in wallet header (displays as @abcdef...xyz for names > 12 chars)
• Fix z-index issue where wallet header was overlapping modals
• Fix TransactionHistoryModal title (was incorrectly showing "Payment Requests")
• Fix swap section ( was showing incorrect token to swap )

Local storage needs to be cleared before testing due to made changes

Test plan

• Send a payment request to the wallet and verify the modal opens automatically
• On mobile view, verify it switches to the wallet tab when payment request arrives
• Test with a long nametag (>12 chars) and verify it truncates correctly with tooltip showing full name
• Verify Payment Requests modal displays correctly without header overlap
• Open Transaction History and verify title shows "Transaction History"
• Swap all token into one ( for example UCT ), export the wallet, logout, import wallet and check the swap section. It should allow to swap UCT for any other token
