[Domain] DNS Management Improvements

[RichardAnderson]

This pull request introduces support for DNS record priority, refactors validation logic, and improves clipboard functionality in the frontend. The most significant changes are grouped below:

DNS Record Priority Support

• Added a new nullable priority field to the dns_records table via a migration and updated the DNSRecord model to include this property in fillable and cast arrays. [1] [2] [3] [4]
• Updated DNS record creation, updating, syncing, and Cloudflare provider logic to handle the new priority field. This includes reading, saving, and passing priority where applicable. [1] [2] [3] [4] [5]
• Modified the DNSRecordResource to expose the priority field in API responses.

Validation Refactoring

• Extracted DNS record validation rules into a new DNSRecordRules class, centralizing and updating rules to include the priority field.
• Updated CreateDNSRecord and UpdateDNSRecord actions to use the new validation rules class. [1] [2]

Cloudflare Provider Enhancements

• Refactored Cloudflare provider to use a buildPayload method for creating/updating records, ensuring consistent handling of the new priority field. [1] [2] [3]

Frontend Clipboard Improvements

• Replaced custom clipboard logic in copyable-badge.tsx with a reusable useClipboard hook, and updated UI feedback. [1] [2]
• Updated DNS record columns to use a new CopyableText component for improved clipboard handling and visual feedback. [1] [2]

• TXT entries now utilise a TextArea instead of a Input

• MX entries now support Priority

• Proxy only appears when the provider supports it, and only on the types of records that it is supported on.
• Where proxy is enabled, a "lock" icon appears next to the content, instead of a whole column.

DNS Provider Registration Extensions

• Extended DNS provider registration to support proxyTypes and supportsCreatedAt configuration, updating relevant service provider and plugin logic. [1] [2] [3] [4]
• Configured Cloudflare to support A, AAAA and CNAME records for proxying.

Pull request overview

This PR enhances the domain DNS management feature by adding MX priority support end-to-end (DB/model/API/provider/UI), centralizing DNS record validation, and improving frontend UX around copying values and provider-specific capabilities.

Changes:

• Added nullable priority to DNS records (migration/model/resource/actions/provider parsing/payload).
• Refactored DNS record validation into DNSRecordRules and updated create/update actions to use it.
• Frontend updates: provider-aware columns/proxy UI, TXT uses textarea, new clipboard hook + new copy UI patterns.
