Danny White 3a72b128de chore(studio): standardise key-value field array partial-row validation (#44411)
## What kind of change does this PR introduce?

Design system and validation consistency update.

## What is the current behaviour?

`KeyValueFieldArray` already renders per-cell form messages, but each
consumer still decides its own validation rules. At the moment, some
consumers allow partially filled rows to submit silently, while Log
Drains now treats them as inline validation errors.

## What is the new behaviour?

This PR standardises the recommended partial-row behaviour for the
current `KeyValueFieldArray` consumers by introducing a shared
validation helper and using it from each form schema.

- adds `getKeyValueFieldArrayValidationIssues` alongside
`KeyValueFieldArray`
- keeps `KeyValueFieldArray` presentation-only and leaves validation in
consumer schemas
- shows inline errors when one side of a key/value row is filled and the
other is empty
- keeps fully empty rows as draft rows
- keeps duplicate-key validation in Log Drains, where it already applies
- updates the design-system docs and examples to describe the validation
pattern explicitly

## Summary by CodeRabbit

* **New Features**
* Added reusable key/value validation utilities and public export; forms
now trim header/key/value inputs, show inline errors for partially
filled rows, and remove fully empty draft rows on submit.

* **Documentation**
* Clarified the field-array is rendering-only and added guidance for
placing validation in form schemas and handling draft rows.

* **Tests**
* Added unit and integration tests covering validation rules, duplicate
keys, trimming, draft-row stripping, and payload behavior.

Writing components

Where to create your components

  • For components that declare the general structure and layout of a page:
    • /components/layouts/xxx
  • For components that are tightly coupled to a specific interface:
    • /components/interfaces/xxx
  • For components that are meant to be reusable across multiple pages:
    • /components/ui/xxx
  • Note: We're gradually moving files out of the to-be-cleaned folder into the respective folders as we refactor

Component structure

  • If a component has constants and utility methods that are tightly coupled to itself, keep them close to the component and enclose them in a folder with an index.tsx as an entry point
  • Otherwise it can just be a file on its own
  • For example:
    • components/ui
      - SampleComponentA
        - SampleComponentA.tsx
        - SampleComponentA.constants.ts
        - SampleComponentA.utils.ts
        - SampleComponentA.types.ts
        - index.ts
      - SampleComponentB.tsx
      

Template for building components


// Declare the prop types of your component
interface ComponentAProps {
  sampleProp: string
}

// Name your component accordingly
const ComponentA = ({ sampleProp }: ComponentAProps) => {
  return <div>ComponentA: {sampleProp}</div>
}

export default ComponentA
