The ManageLocalization class was throwing a PHP Fatal error due to an incompatible method signature between its form() method and the parent SettingsPage class.

Problem

The error occurred because:

// ManageLocalization was using (incorrect):
public function form(Filament\Forms\Form $form): Filament\Forms\Form

// But SettingsPage expects (correct):  
public function form(Filament\Schemas\Schema $schema): Filament\Schemas\Schema

This caused the fatal error:

PHP Fatal error: Could not check compatibility between Cachet\Filament\Pages\Settings\ManageLocalization::form(Filament\Forms\Form $form): Filament\Forms\Form and Filament\Pages\SettingsPage::form(Filament\Schemas\Schema $schema): Filament\Schemas\Schema

Solution

Updated ManageLocalization to match the pattern used by all other settings pages (ManageCachet, ManageCustomization, ManageTheme):

1. Import changes: Replaced Filament\Forms\Form with Filament\Schemas\Schema and individual component imports
2. Method signature: Changed to form(Schema $schema): Schema
3. Component usage: Updated from Forms\Components\* namespace to direct component imports
4. Method call: Changed from ->schema([...]) to ->components([...])

The fix maintains all existing functionality while resolving the fatal compatibility error and ensuring consistency across all settings pages.

This pull request was created as a result of the following prompt from Copilot chat.

The ManageLocalization class in the Cachet\Filament\Pages\Settings namespace is throwing a PHP Fatal error due to an incompatibility between the method signature of form() and its parent class Filament\Pages\SettingsPage.

The error specifically states:

PHP Fatal error:  Could not check compatibility between Cachet\Filament\Pages\Settings\ManageLocalization::form(Filament\Forms\Form $form): Filament\Forms\Form and Filament\Pages\SettingsPage::form(Filament\Schemas\Schema $schema): Filament\Schemas\Schema, because class Filament\Forms\Form is not available in /home/runner/work/core/core/src/Filament/Pages/Settings/ManageLocalization.php on line 24

Steps to Fix:

1. Update the method signature of form() in ManageLocalization to match the parent class SettingsPage. Replace the parameter type Filament\Forms\Form with Filament\Schemas\Schema.
2. Ensure that Filament\Schemas\Schema is properly imported in the ManageLocalization.php file.
3. Test the fix to ensure that the ManageLocalization page functions correctly without the fatal error.
