9952d6f10f [FE-4067] fix(studio): re-allow all regions in local project creation (#48704)
Local dev stacks can run in any of the three supported regions (e.g.
Bobbie's is in `ap-southeast-1`), but enabling High Availability on the
project creation form pinned local to Frankfurt only. This unrestricts
local so all three regions are selectable again.

**Changed:**
- `getHighAvailabilityRegionCode()` returns `undefined` for `local`
(same as prod), so `filterHighAvailabilityRegions()` no longer collapses
the list — staging stays pinned to `us-east-1`
- The three-region warning in `RegionSelector` now adds a local-only
recommendation: "Use Central EU (Frankfurt) unless you're on a personal
dev stack."
- Updated unit tests, including an `ap-southeast-1` fixture region to
prove pass-through

## To test

- On a local stack, open the new project form and enable High
Availability — the region selector should offer all three regions (East
US, Frankfurt, Southeast Asia) instead of locking to Frankfurt, and the
warning should recommend Frankfurt unless you're on a personal dev stack
- Confirm staging behavior is unchanged (HA still pins to East US)
- `pnpm --filter studio exec vitest run
components/interfaces/ProjectCreation`

## Summary by CodeRabbit

* **Bug Fixes**
* Local development projects can now use high-availability regions
beyond Central EU.
* Region filtering and availability messaging now correctly reflect the
active environment, including staging restrictions.

* **User Experience**
* Added guidance recommending Central EU for local projects, unless
using a personal development stack.
* Region selection now provides clearer environment-specific information
when options are limited.

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 — use a named export, not a default export
export const ComponentA = ({ sampleProp }: ComponentAProps) => {
  return <div>ComponentA: {sampleProp}</div>
}
