Fix form render crash and invalid Flatpickr locale

[coolsam726]

Summary

• Fix Blade view calling $isReadOnly() after it was already evaluated to a bool, which caused "Value of type bool is not callable" when opening forms
• Fix Flatpickr JS locale import so bundled l10n locales are read from the default export, preventing "invalid locale undefined" at init
• Rebuild the dist Alpine component bundle

Test plan

• vendor/bin/pest — 114 tests pass
• Open a Filament form with Flatpickr::make() fields (date, datetime) and confirm the form loads without PHP or JS errors
• Confirm the picker opens and selects dates correctly
