Subdomains use allocation alias option

[gavidroselj]

• Adds a per-node setting to use allocation aliases instead of allocation IPs for A/AAAA records
• Unifies record requirement checking in one function, so it's no longer duplicated

Closes #123

Summary by CodeRabbit

• New Features

  • Administrators can configure nodes to use allocation aliases instead of allocation IPs for DNS records.

  • Improved DNS handling for servers without a primary allocation.

• Documentation

  • Added guidance on allocation aliases, including IPv4/IPv6 requirements and recommended usage.

• Localization

  • Added English and German labels for the allocation alias setting.

📝 Walkthrough

Walkthrough

The change adds a node-level allocation alias setting, centralizes record-type validation, and uses the selected allocation address for DNS records. It also adds migration support, translations, documentation, and an administrative toggle.

Changes

Allocation Alias Support

Layer / File(s)	Summary
Alias configuration and administration subdomains/database/migrations/010_add_alias_toggle_to_nodes.php, subdomains/src/Filament/Admin/Resources/SubdomainTargets/SubdomainTargetResource.php, subdomains/lang/*/strings.php, subdomains/README.md	Adds the subdomain_use_alias node column, an administrative toggle, English and German labels, and documentation for the setting.
Record type validation subdomains/src/Enums/RecordType.php, subdomains/src/Models/CloudflareDomain.php	Adds centralized validation for permissions, allowed record types, allocations, target addresses, subdomain targets, and SRV service types. availableRecordTypes uses this validation.
Alias-aware record creation subdomains/src/Models/Subdomain.php	Uses centralized validation, selects ip_alias or ip from the allocation, and shares prefixed names across record payloads.

record-selection logic around RecordType to resolve the address only for
IP-based record types after validating allocation; in

within the A and AAAA paths while retaining the guarded allocation lookup needed
for SRV port access. CNAME handling must remain allocation-independent.

Authorize the node before saving the toggle.

updateStateUsing calls forceFill(...)->save() without an explicit update-policy check. If Filament does not enforce the Node update policy for inline column updates, a user who can access this table without node-update permission can change subdomain_use_alias, which controls the DNS target used by the record flow. Add the same user()?->can('update', $node) check before saving, or use an authorized update path.
