Add manual wallet unlock button and metadata display

Improve NIP-60 wallet viewer UX:

- Replace auto-decrypt with manual "Unlock Wallet" button:
  * Gives users control over when to decrypt sensitive data
  * Prevents automatic decryption on page load
  * Shows clear "locked" state until user clicks unlock

- Add comprehensive wallet metadata display after unlock:
  * Wallet name and description
  * Unit (sat, usd, etc.)
  * Configured mints with full URLs
  * Configured relays
  * Wallet private key (truncated for security)
  * Warning about keeping private key secure

- Enhance decryption error handling:
  * Add "Retry" button when decryption fails
  * Show loading state with spinner during decryption
  * Display detailed error messages
  * Console logging for debugging

- Improve status indicators:
  * Clear locked/unlocked visual states
  * "Decrypting..." message with spinner
  * Better error display with retry option
  * Event count status grid

This provides users with full visibility into their wallet
configuration after unlocking, including all mints, relays,
and the wallet private key used for Cashu operations.
