fix(docker): correct permissions and fix migration barcode_type error (#4546)

* fix(ci): include hidden files in Docker build context

actions/upload-artifact@v4 excludes hidden files (dotfiles) by default,
causing .htaccess files to be missing from the Docker image. Add
include-hidden-files: true to preserve .htaccess in the build artifact.

* fix(docker): correct permissions and add barcode_type default

- Set proper permissions (750) for writable/logs, writable/uploads,
  writable/cache, public/uploads, and public/uploads/item_pics
- Set permissions (640) for writable/uploads/importCustomers.csv
- Add barcode_type default value to prevent 'unknown key' error
  during initial migration when database is not yet initialized
