Add Korean LP dictionary and PGNet config

- dict/kr_lp_dict.txt: 67 chars covering 4 plate types
  (10 digits + 40 usage hangul + 17 region hangul, dedup)
- configs/kr_lp_pgnet.yml: PGNet config tuned for Korean LP
  (pad_num=67, max_text_length=10, valid_set=partvgg, infer_visual_type=CN)
- setup_server.sh: symlink dict and config into PaddleOCR tree
