feat: convert all file inputs to FilePond for standardized uploading

- Add csv_import queue type (storeAsFile, no async upload) for CSV import dialog
- Convert file-field.php partial to FilePond with field-name→queue-type mapping
- Conditionally skip server config for storeAsFile queues in buildFilePondOptions
- Skip FilePond init for inputs inside closed <dialog> elements
- Trigger FilePond init when import dialog opens
- Load FilePond CSS/JS assets on admin index page
