PLU-344: chore: add mock data improvements (#800)

## Problem

Some fields are either missing or not user-friendly for mock data

## Improvements
- Standardise email field types to the user email so it could be used in
postman step
- Add corppass missing info
- Reference:
https://github.com/opengovsg/FormSG/blob/82c5ba6fff7e9628b6c32449148e89c0224e9ff5/src/app/modules/spcp/spcp.util.ts#L92
- Can refer to this pipe in production for example:
9777d71f-dbac-47c4-a70a-c18f02e3a7bc
- Hide NRIC collection if disabled
- Add mock payment data if the form has payment enabled
- For `Products` payment_type: take the first payment product available
in the form setup (`Product or service`)
- For `Variable` payment_type: mock a default product name and amount to
be returned (`Respondents choose what to pay`)

## Tests (for mock data)
- [x] Old and standard forms still work (no payment, singpass or
corppass)
- [x] Payment forms work (test using staging form, can add payments
without a stripe account)
- [x] Singpass forms still work with or without verified NRIC
- [x] Corppass forms will return the verified NRIC and UEN
