Fix: "Unable to retrieve the file_size" on file upload (Filament 5 / Livewire)

[xchimx]

Description
This PR fixes an issue where successful file uploads are logged and treated as errors, throwing Unable to retrieve the file_size for file at location: livewire-tmp/....

Root Cause
With recent Livewire versions (especially noticeable after upgrading to Filament 5), temporary files are moved/deleted immediately upon calling $file->storeAs().
Because the Log::info block directly after storeAs() tried to fetch $file->getSize() and $file->getMimeType() from the temporary livewire-tmp path, Flysystem threw a UnableToRetrieveMetadata exception.

Solution
I simply reordered the logic to retrieve the file metadata (size and mime_type) before storeAs() is executed. This prevents the exception and allows the upload flow to complete successfully.
