Implement manual domain expiry overrides, improve subdomain discovery via CT logs, and enhance the monitoring dashboard with favicons and configurable display options.

hub:
- allow manual expiry and creation date overrides in domain API when WHOIS lookup fails
- implement JSON parsing for crt.sh certificate transparency log searches in subdomain discovery
- update monitor API routes to use curly brace syntax for path parameters

site:
- add manual registration date and period inputs to domain dialog
- implement monitor favicon support using Google's favicon service
- add configurable display options (uptime pills, heartbeat dots) to monitors table
- update localization files to include new UI elements
