Danny WhiteandJoshen Lim fce9d475ee chore(studio): migrate combobox triggers (#50157)
## What kind of change does this PR introduce?

Studio UI consistency refactor.

## What is the current behaviour?

Several Studio comboboxes still build their triggers from `Button` and
supply their own double-chevron icon. This duplicates trigger styling
and allows these controls to drift from selects and other comboboxes.

## What is the new behaviour?

- Migrates the PITR timezone, AWS region, and account timezone controls
to `ComboboxTrigger`
- Migrates the shared `SchemaSelector` and `FunctionSelector`, updating
their Studio callsites together
- Preserves the globe icon in both timezone controls
- Exposes the correct combobox role and open state through the shared
trigger
- Tightens the tiny schema selector end padding so its chevron aligns
with adjacent controls
- Leaves organisation and project context switchers unchanged

## To test

On the [Studio
preview](https://studio-staging-git-dnywh-choremigrate-combobox-680102-supabase.vercel.app):

1. Open **Database > Tables** and use the schema selector above the
table. It should use a single down chevron, open normally, and update
the selected schema.
2. Open **Authentication > Hooks > Add hook**, then select **Postgres**
as the hook type. The **Postgres schema** and **Postgres function**
selectors should use a single down chevron and continue to open and
select normally.

The PITR, AWS region, and account timezone callsites require the
relevant plan, integration, or feature flag. When available, their
triggers should use the same single down chevron, and both timezone
controls should retain the globe icon.

## Summary by CodeRabbit

* **UI Improvements**
* Standardized timezone, AWS region, database backup, function, and
schema selectors with a consistent combobox interface.
  * Added clear visual feedback for open and closed selector states.
* Preserved contextual icons and labels, including globe icons for
timezone selections.
* Improved accessibility with appropriate combobox semantics, accessible
names, and state information.
* Timezone settings are now available without an optional feature flag.
* **Tests**
  * Updated end-to-end coverage for the standardized combobox controls.
* Added coverage confirming schema selectors expose the selected schema
as an accessible name.

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>
}
