feat(dns): add functions to handle missing DNS records and mark records as synced

- Introduced `isMissingCfDnsRecord` to identify missing Cloudflare DNS records based on error messages.
- Added `markSynced` function to update DNS record fields in the database and return the updated record.
- Refactored `pushRecord` to utilize `markSynced` for better code organization and clarity.
- Enhanced error handling for cases where DNS records need to be recreated after manual edits.
