refactor(numbering-rule): NumberingRule → Input canonical 흡수 + 채번 관리 페이지 분리

- 옛 registry/numbering-rule, registry/v2-numbering-rule, V2NumberingRuleConfigPanel,
  NumberingRuleTemplate 폐기 — InvFieldConfigPanel + InputComponent 로 통합
- input 에 numbering-picker / select-pickers 추가, autonum 타입 흡수
- 채번 관리 전용 admin 페이지(systemMng/numberingRuleList) + CreateDialog +
  SequenceManagementPanel 신설
- backend NumberingRule controller/service/mapper 갱신 (시퀀스 관리 엔드포인트)
- input canonical 진행 노트 + 채번 관리 mockup 추가
