Fix uploads over 4 GB failing with a misleading size error

Browse Source 
Livewire's temporary upload rule was hard-coded to max:4194304 (4 GB),
so /livewire/upload-file rejected any larger file no matter how high
PHP_UPLOAD_MAX_FILESIZE or the admin's max file size were set.
_uploadErrored() then replaced Livewire's actual message with "file
exceeds the maximum size of N MB", quoting the admin limit the file was
under.

The cap is removed: PHP's upload_max_filesize is the hard limit and the
admin setting is still enforced in updatedFiles() and createShare(). A
rejected upload now logs the real validation errors and tells the user
the server could not accept the file.

max_upload_time is configurable via LIVEWIRE_MAX_UPLOAD_TIME, and the
README documents every limit large uploads depend on.
