Fix TypeScript build errors in studio frontend (#4429)

Browse source 
- tool-ui-python.tsx: use explicit tuple type instead of `as const` to
  match the mutable `[BundledTheme, BundledTheme]` expected by Streamdown
- chat-adapter.ts: add missing `argsText` field required by
  ToolCallMessagePart and fix `args` type to use ReadonlyJSONObject
