Charis 0daafca2ca feat(studio): status page banner (incident / maintenance / upcoming) (#51044)
## Summary

* Adds a new global status banner (`StatusBanner`) driven by the
[incident.io](<http://incident.io>) status page data, showing at most
one of: an active incident, in-progress maintenance, or upcoming
maintenance, in that priority order.
* All three types are independently dismissible (persisted to a new
localStorage key, `status-banner-dismissed-keys`); dismissal hides the
banner for items still active, and a new incident reappears even if a
related item was previously dismissed.
* Only shows to users who are actually affected (based on their
projects' regions) or when region data is incomplete (fails open), and
is bypassed entirely by the existing emergency incident override.
* Behind the existing `incidentIoStatusPage` ConfigCat flag —
`AppBannerWrapper` renders this new banner instead of the legacy
`StatusPageBanner` only when the flag is on; default behavior is
unchanged.
* This is PR 5b in a stacked series for Linear
[FE-4057](https://linear.app/supabase/issue/FE-4057) — see that issue
for full design context.

## Test plan

* New unit tests (`StatusBanner.utils.test.ts`) covering
banner-selection priority, dismissal-key handling, and copy generation
* New MSW component test (`StatusBanner.test.tsx`) covering loading
state, dismiss-and-persist, and the emergency-override path
* `pnpm --filter studio run typecheck`, `lint:ratchet`, `pnpm knip
--workspace apps/studio`, `pnpm test:prettier`, and relevant vitest
suites all pass

## Summary by CodeRabbit

* **New Features**
* Added status banners for relevant incidents and scheduled maintenance,
including incident details, maintenance timing, and links to the status
page.
* Banners can be dismissed, and dismissed items stay hidden while new
incidents or maintenance updates can still appear.
* Upcoming maintenance banners appear within the relevant lead time, and
maintenance timing is shown when available.
* Emergency overrides display a warning banner without a dismiss option.

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>
}
