fix(lychee): preserve uploads and ownership during update

The update script wiped public/uploads and did not re-apply www-data
ownership, causing HTTP 500 after successful updates. Align with upstream
upgrade steps and sibling Laravel scripts by backing up uploads/dist,
restarting PHP-FPM, running full artisan cache cycle, and adding verbose
diagnostics.

Fixes #15763
