fix: strip admin plugin IO schemas (#7141)

* refactor(core): optimize system tool input/output schema management

- Use `JSONSchema` instead of `InputConfig` for system tool I/O
  definitions
- Centralize JSON Schema to Node I/O conversion utilities
- Cleanup redundant type definitions and schema properties across
  packages

* refactor(global): improve workflow JSON schema mapping and tool catalog

- Update `getJsonSchemaPropertyFromValueType` to handle complex types
  like `arrayObject` and `chatHistory` properly instead of falling back
  to default types.
- Refactor `getEnumValuesFromNodeInput` to correctly collect enum values
  from different input configurations.
- Update `useToolCatalog` to use `nodeInputs2JsonSchema` for consistent
  schema generation across tools and nodes.
- Add comprehensive test cases to verify JSON schema conversion for
  various value types and enum sources.

* fix: strip admin plugin IO schemas

Admin plugin detail does not consume input/output schemas, so omit them from the admin response type to tolerate plugins that return null schemas.\n\nAdd regression coverage for parent and child tool details with null schemas.
