Kanishk Dudeja 1f03c0dc0e fix(billing): trim Tax ID inputs to trigger required validation (#47311)
### Summary

This PR trims the Tax ID value on the frontend so that whitespace-only
entries (e.g. " ") are correctly treated as "not set" instead of a valid
value.

Previously the "is the Tax ID set?" checks relied on string
length/truthiness, so whitespace-only input slipped through as a real
value - bypassing validation and getting persisted.

### Testing

- Subscription upgrade & top-up forms: verified the form no longer
submits when only whitespace is entered for the Tax ID. The validation
message now shows.
- Billing address form: no inline message is shown, but the Tax ID is
submitted as null, which clears it. This is unchanged from current
behaviour.

## Summary by CodeRabbit

* **Bug Fixes**
* Tax ID values are now trimmed before validation and submission,
reducing errors caused by accidental leading or trailing spaces.
* Billing and payment flows now consistently use the cleaned Tax ID
value when deciding whether to save or send it.
* Customer tax ID details passed to payment setup now reflect the
trimmed value, helping avoid mismatches with external payment
processing.

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
const ComponentA = ({ sampleProp }: ComponentAProps) => {
  return <div>ComponentA: {sampleProp}</div>
}

export default ComponentA
