Restructure documentation navigation and file organization

- Reorganize nav to: Getting Started, Concepts, Schema Design,
  Data Types, Data Operations, Queries, Administration, Reference
- Create datatypes/ section (blob, attach, filepath, object, adapters)
- Merge manipulation/ + compute/ into operations/
- Move sysadmin/ to admin/
- Consolidate concepts to minimal index linking to DataJoint Book
- Remove theoretical pages (normalization, integrity, recall)
- Move reference files (faq, develop, citation, transpilation)
