Reconcile and verify BIP353 DNS records

[Alex71btc]

Summary

Improves BIP353 DNS handling and diagnostics for Cloudflare-managed setups.

Public BOLT12 address

• Checks the configured public BIP353 TXT record against Cloudflare.
• Prompts the user before recreating a missing record instead of silently writing DNS.
• Rechecks before repair to avoid races or duplicate writes.
• Keeps existing invalid/foreign TXT records untouched.
• Adds DE/EN repair UI to Console, Setup and Pay pages.
• Keeps the standard BOLT12 address and QR usable while DNS is missing.

Published BIP353 records

• Adds manual verification for published Alias Manager records.
• Skips unpublished/draft aliases.
• Adds manual verification for BIP353 addresses published from Offer History.
• Distinguishes:
  • correct
  • missing
  • invalid
  • offer mismatch
  • lookup errors
• Verification is read-only and does not modify DNS records.

TXT parsing

• Handles long BIP353 TXT records split into multiple quoted DNS character strings.
• Prevents valid Cloudflare TXT records from being falsely reported as containing a different offer.

Diagnostics

• Improves NWC logging while avoiding unnecessary exposure of long cryptographic identifiers.
• Redacts BIP353 domains in logs while keeping the username useful for troubleshooting.

Testing

• Python syntax checks passed.
• git diff --check passed.
• Docker Compose configuration validation passed.
• Tested locally with Cloudflare-managed BIP353 records.
• Verified correct detection of existing Alias Manager records.
• Verified correct detection of Offer History BIP353 records.
• Verified German and English UI.
• Verified split Cloudflare TXT records are recognized correctly.
