- Adds validations for imported CSV data
- These checks include obvious validation checks for data - like if email addresses are valid, checking if Stripe configured when entries with stripe_customer_id are present and additional server-side validation for entries with stripe_customer_id to check if they appear in connected Stripe account
- The validation set is calculated by naive choosing of first 5, middle 5 and 5 tail records from imported set. This logic comes from observations that errors usually apear withing "test" records in the beggining or the end of the file. These selection rules might change in the future if we find a need for it.
- Adds papaparse CSV parser, which was chosen for it's maturity and relatively small minified size. In the future this library should be lazy-loaded to make the first page load UX nicer
no issue
- when confirming email send, after initial save in, poll every second for a maximum of 10 seconds and check the status of the email
- if it's `'success'` close the modal immediately
- if it's `'failure'` switch the confirm modal to an error state
- if the save fails for some other reason (validation, server error) close the modal immediately and let the normal editor error handling do it's thing
- fixed confirm modal not appearing when retrying a save after a post validation failed
- show email status in post status area
- `"and sending to x members"` when email is pending or submitting
- `"and sent to x members"` once email is fully submitted
