fix: OAuth DCR scope field compliance
Omits the scope field entirely when undefined, per RFC 7591. This allows OAuth servers to assign default scopes instead of registering clients with no scopes.
Tested with Keycloak DCR.
- Align tests with new form-first rendering and UI behavior:
- Labels prefer schema `title` over property key.
- Descriptions shown for boolean checkboxes and select fields.
- Explicit mode switching between Form/JSON when needed.
- Add comprehensive coverage for enum schema variants:
- Titled single-select via `oneOf`/`anyOf` with `{ const, title }`.
- Untitled single-select via `enum` (with legacy `enumNames` labels).
- Untitled multi-select via `items.enum` with `minItems`/`maxItems` helper text.
- Titled multi-select via `items.anyOf`/`oneOf` with `{ const, title }`.
- Adjust complex/JSON-mode tests to click “Switch to JSON” before asserting textarea and clipboard interactions.
- Fix debounced JSON update expectations to assert parsed objects rather than raw text.
Files updated:
- `client/src/components/__tests__/DynamicJsonForm.test.tsx`
- `client/src/components/__tests__/DynamicJsonForm.array.test.tsx`
In DynamicJsonForm.tsx,
- Support all five enum shapes used by MCP SDK:
- Titled single-select via `oneOf`/`anyOf` with `{ const, title }`
- Untitled single-select via `enum`
- Titled legacy single-select with optional `enumNames` for labels
- Titled multi-select via `items.anyOf`/`oneOf`
- Untitled multi-select via `items.enum`
- Show field descriptions for string select fields and boolean checkboxes (consistent help text above inputs).
- Prefer schema property `title` for object field labels; fall back to the JSON key when missing.
- Allow top‑level form rendering for objects with properties, arrays with items, and primitive types (was overly strict before).
- Multi-select UI: sensible list size and `minItems`/`maxItems` helper text when present.
- JSON editor fallback, copy/format controls, and debounced parsing preserved.
- apply defaults for optional fields during form init
In schemaUtils.ts
- `generateDefaultValue` now includes optional properties that declare a `default`, ensuring fields like strings show their defaults on first render.
In jsonUtils.ts
- Add legacy `enumNames?: string[]` and array constraints `minItems?`/`maxItems?`.
* In DynamicJsonForm.tsx
- In debouncedUpdateParent, formatJson, and validateJson,
- when trimming the JSON value, use ?.trim() in case the field is null
* In jsonUtils.ts
- in tryParseJson
- use ?.trim() in case the field is null
* In schemaUtils.ts
- in normalizeUnionType
- add condition to handle the case where there is an anyOf with array or null as options
* In ToolsTab.tsx
- for nullable fields, in null checkbox, in onCheckedChange handler
- when not checked, if prop type is array, set to undefined (empty input field that can be edited rather than the word "null" as the default could provide
