feat: add document requirements and form schema management for license types

- Implement DocumentRequirementsTab for managing document upload requirements.
- Create FieldEditorDrawer and SectionEditorDrawer for editing fields and sections in the form schema.
- Develop FormSchemaTab to handle sections and fields for a license type's form schema.
- Introduce CertificateRequirementsPage to serve as the main interface for configuring license type requirements.
- Add hooks for requirement actions to streamline mutation handling and notifications.
- Implement condition handling for fields and sections to manage visibility based on user input.
- Create schema-paths configuration to facilitate condition target collection.
