## Problem
Sentry reporting permission-denied errors on `/open-banking/callback`:
> UnexpectedValueException: The stream or file
"/app/storage/logs/laravel.log" could not be opened in append mode:
Failed to open stream: Permission denied
4 issues, 14 events (PHP-LARAVEL-Z, 10, 11, 12).
## Root cause
Entrypoint runs as root. After the initial `chown www-data`, artisan
commands (`config:cache`, `route:cache`, `view:cache`, `event:cache`,
`migrate`) execute and can create/touch `storage/logs/laravel.log` as
root. Later, php-fpm (www-data) tries to append and fails.
Queue workers + inertia-ssr also run as root via supervisor — same
failure mode from worker side.
## Fix
- `docker/entrypoint.sh`: re-chown `/app/storage` and
`/app/bootstrap/cache` to www-data **after** artisan cache warm-up, just
before `exec supervisord`.
- `docker/supervisor/supervisord.conf`: add `user=www-data` to
`queue-worker`, `queue-worker-emails`, `inertia-ssr`. Nginx and php-fpm
master keep root (need port 80 / pool forking).
## Verification
Deploy and confirm Sentry issues stop firing on next
`/open-banking/callback` hits.
