Summary of Changes

Hello @ajaysehwal, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the Nostr Wallet Connect (NWC) functionality by empowering users to configure and utilize custom Nostr relay servers. This core feature improves the flexibility and decentralization of NWC connections within the application. Complementing this, the PR also includes essential updates to iOS project dependencies and deployment targets, ensuring the application remains compatible and performs optimally on newer iOS versions.

Highlights

• Custom Nostr Relays Support: Introduced the ability for users to specify and connect to custom Nostr relay URLs for Nostr Wallet Connect (NWC) connections, enhancing flexibility and decentralization.
• NWC Connection Data Model Update: The NWCConnection data model now includes a customRelayUrl field to store user-defined relay addresses, ensuring persistence of custom configurations.
• Enhanced User Interface for Relay Selection: The 'Add/Edit NWC Connection' screen has been updated with a new input field for custom relay URLs. This field dynamically appears when the 'custom' option is selected in the relay dropdown, providing an intuitive user experience.
• Client-Side Relay URL Validation: Implemented client-side validation for custom Nostr relay URLs to ensure they adhere to a valid wss:// or ws:// format, preventing malformed entries.
• iOS Project Dependency and Deployment Target Updates: Updated several iOS dependencies, including SwiftProtobuf, DoubleConversion, and glog. Additionally, the IPHONEOS_DEPLOYMENT_TARGET has been significantly increased to newer versions (15.6 and 26.0) across various build configurations, ensuring compatibility and leveraging modern platform features.
