fix(esigner-api,esigner): show only explicit signing containers in eSigner list, not all files from File Manager

- esigner-api: getDocumentsWithStatus(userId, listMode). list=containers (default):
  only files with at least one signee; list=all: all owner/invited files
- FileController.getFiles: read query param list=all and pass listMode
- esigner new container page: load selectable files via GET /api/files?list=all
  into local state so picker shows any file; main list unchanged (containers only)
