Joshen Lim ad30c04e0e Persist last visited explorer tab (#50557)
## Context

Saves the last visited explorer tab via `useDashboardHistory`, such that
landing back on `/explorer` will open the last visited page. Similar
behaviour to Table Editor and SQL Editor

Would also be useful when going between the SQL Editor and Explorer to
bring snippets over

## Summary by CodeRabbit

* **New Features**
* Explorer now remembers and restores the last visited query, chat, or
notebook tab.
* Automatically returns to the Explorer home screen when a saved tab is
unavailable.
* Displays a loading state while the last visited tab is being restored.

* **Bug Fixes**
  * Closing deleted chat tabs now clears their saved history.

* **Tests**
* Added coverage for Explorer tab restoration, loading states, and stale
history cleanup.

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>
}
