feat: add NIP-62 Request to Vanish screen

Add a new screen allowing users to send NIP-62 relay deletion requests. Users can select a specific relay or ALL RELAYS, pick a date (data created before that date will be requested for deletion), and provide an optional reason. Includes confirmation dialog with clear warnings about the irreversible nature of vanish requests. https://claude.ai/code/session_019Xrprdfq6pVN8beYrYUSr4
