fix:History UI improvments

[0xCardiE]

Upload History Improvements

ENS Note Relocation

• Moved "Click on ENS button to link reference to your ENS domain" note from header to above the item list
• Added info icon (ℹ️) alongside the note for better visibility

Clear Expired Items Button

• Added new "Clear Expired Items" button with hourglass icon next to "Clear History"
• Button only appears when there are expired items in history
• Tooltip displays count of expired items (e.g., "Clear 5 Expired Items")
• Shows confirmation dialog with item count before deletion
• Removes only expired items while keeping valid ones

Automatic History Update on Stamp Top-Up

• History items now automatically update their expiry dates when a stamp is topped up
• New expiry calculation: existing expiry + additional days purchased
• Runs immediately after successful top-up (no network delay)
• Works reliably even if user navigates away after top-up confirmation
