Joshen Lim 71d58cba7f Joshenlim/fe 4401 re sql editor silently points to the primary instead of (#50513)
## Context

Fixes the following 2 issues with the database selection in the SQL
Editor
- An errant `useEffect` was resetting the `selectedDatabaseId` back to
the primary every time the `databases` list from `useReadReplicasQuery`
changed reference (not just on first load).
- `QuerySourceMenu` kept showing "Read Replica" even after selection had
reverted
- Was using local storage value as the `identifier` for
`DatabaseParametersSubMenu`, when it should use the valtio store as the
source of truth

## Summary by CodeRabbit

- **Improvements**
- The SQL Editor now remembers the last selected database between
sessions.
- Your saved database selection is restored when available; otherwise,
the project’s primary database is selected automatically.
- Query source settings now stay synchronized with the database
currently selected in the SQL Editor.

- **Bug Fixes**
- Background database refreshes no longer unexpectedly reset your
selected read replica to the primary database.
- Database selection now waits for saved preferences to load, preventing
a brief incorrect selection.

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>
}
