Editing Customer Group availability on a Product

[PharaohAsh]

• Lunar version: 1.0.0-beta6
• Laravel Version: 11.39.0
• PHP Version: 8.3
• Database Driver & Version: PostgreSQL 16.2

Expected Behaviour:

I should not encounter an error by toggling any of the options for Customer Group in a product.

Actual Behaviour:

Toggling off any of the Customer Group's options:

• Purchasable
• Visible
• Enabled

causes the page to crash with the following error:

[previous exception] [object] (UnhandledMatchError(code: 0): Unhandled match case '' at /vendor/lunarphp/lunar/src/Filament/Resources/ProductResource/RelationManagers/CustomerGroupRelationManager.php:81)

Steps To Reproduce:

1. Go in to edit a product.
2. Click on Availability
3. Edit the attached Customer Groups (only one here)
4. Toggle Purchasable OR Visible OR Enabled off
5. Save
