Context

I'm working on a Spanish e-commerce site using Lunar with the table-rate-shipping plugin. I've successfully translated most of the admin panel to Spanish, but I've encountered an issue where one specific navigation label cannot be translated.

What I'm Trying to Do

I need to translate the "Edit Shipping Zone" text that appears in the sub-navigation menu when editing a shipping zone. I've already successfully translated all other navigation items using the standard Laravel translation files in lang/vendor/lunarpanel.shipping/es/.

The Problem

The EditShippingZone page class doesn't implement a getNavigationLabel() method, unlike its sibling pages. This causes Filament to auto-generate the label from the class name ("Edit Shipping Zone"), making translation impossible.

What I've Checked

• Reviewed the documentation for translation support
• Checked existing issues for similar problems
• Verified that other pages in the same module work correctly
• Confirmed the issue exists in the latest version
• Attempted workarounds (extending classes, translation overrides)

Steps to Reproduce

1. Install Lunar with table-rate-shipping plugin
2. Set application locale to any non-English language (e.g., 'locale' => 'es')
3. Add translations in lang/vendor/lunarpanel.shipping/es/
4. Navigate to /admin/shipping-zones/{id}/rates
5. Observe the sub-navigation menu

Current Result:

• "Edit Shipping Zone" (Not translated - hardcoded from class name)
• "Tarifas de envío" (Correctly translated)
• "Exclusiones de envío" (Correctly translated)

Expected Result:
All three navigation items should be translated.

Technical Details

Affected File

src/Filament/Resources/ShippingZoneResource/Pages/EditShippingZone.php

Working Example (from same package)

ManageShippingRates.php correctly implements translation:

public static function getNavigationLabel(): string
{
    return __('lunarpanel.shipping::relationmanagers.shipping_rates.title_plural');
}

Proposed Solution

Add the same pattern to EditShippingZone.php:

public static function getNavigationLabel(): string
{
    return __('lunarpanel.shipping::shippingzone.pages.edit.label');
}

Environment

• Laravel: 11.46.1
• Lunar: Latest version
• Lunar Table Rate Shipping: Latest version
• PHP: 8.2+
• Filament: v3

Why This Matters

This inconsistency prevents full localization of the admin panel for non-English users. In my case, it's the only English text remaining in an otherwise fully Spanish interface, which creates a poor user experience for my Spanish-speaking admin users.

Additional Notes

I'm happy to submit a PR with the fix if you agree with the proposed solution. The change would be minimal and follow the existing pattern used by other pages in the same module. [I did it yet, see below]
