Ali Waseem e63cca3b4a fix(studio): preserve EXTERNAL_PHONE_ENABLED on phone provider save (#44982)
## Summary

Toggling the Phone auth provider on in Studio appeared to save (success
toast) but snapped back to **Disabled** immediately. The backend value
never changed.

## Root cause

In `AuthProvidersFormValidation.tsx`, the phone schema's final
`.transform` replaced the parsed values with
`enabledSchema.parse(values)`:

```
.transform((values) => {
  if (values.EXTERNAL_PHONE_ENABLED === true) {
    return enabledSchema.parse(values)   // ← strips EXTERNAL_PHONE_ENABLED
  }
  return values
})
```

`enabledSchema` is a `z.discriminatedUnion('SMS_PROVIDER', [...])` whose
branch schemas (twilio / twilio_verify / messagebird / vonage /
textlocal) don't declare `EXTERNAL_PHONE_ENABLED`. Zod objects strip
unknown keys by default, so the flag was dropped from the submitted
payload. The PATCH request to `/platform/auth/{ref}/config` went out
without `EXTERNAL_PHONE_ENABLED`, the backend kept its previous value,
and `form.reset` on the response snapped the toggle back to disabled.

Regression was introduced in #44865 (zod migration). The recent #44974
fix addressed the `shouldUnregister` side of the form but not this
transform.

## Fix

Spread `enabledSchema.parse(values)` and re-add `EXTERNAL_PHONE_ENABLED:
true` so the flag survives the transform.

## Test plan

- [x] On a project with no phone provider configured, pick an SMS
provider (e.g. Twilio), fill credentials, toggle Phone on, Save → toggle
stays **Enabled**, network tab shows `EXTERNAL_PHONE_ENABLED: true` in
PATCH payload and response
- [x] Toggle Phone off → stays **Disabled** (unchanged behavior)
- [x] Change SMS provider credentials while enabled → saves correctly
- [x] With SMS hook enabled, phone provider fields remain optional as
before

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
