Adding the `button` mixin into `input[type="submit"] caused conflicts with the other button classes (`.button-primary`) due to specificity. The button classes should be used on all buttons instead. This also updates which button on the Manage Pledge form is the "primary" action, since it's easy to skip the Update button when it's not primary.
* Add the admin email field to the manage form
* Fix admin email processing: When the email is changed, the pledge needs to be set back to pending, until the email is re-confirmed
* Send confirmation emails for existing pledges to the "Manage Pledge" page
* Process the email confirmation & resending emails actions on both shortcodes
* Add a message for unconfirmed pledges
* Add contributor management to manage form
* Check `pledge_id` to prevent returning all contributors
* Return a plain text error string – this is used in an alert box, so it can't contain HTML
* Hide confirmation when pledge is a draft
* Only enqueue script if the user is authorized
This broadly enables & styles the pledge forms across the frontend and wp-admin.
- Switches field `readonly` control to a variable called `$readonly`
- Create `PledgeMeta\get_pledge_meta()` which will fetch data from `$_POST`, a pledge post, or defaults.
- Add Number of Employees field
- Update form content to match mockup:
- fields now have help text
- success message uses content from mockup
- logo field is moved to the "org info" section
- Style form in theme, add some similar styles to the admin
