add toggle buttons to pub field form elements

[3mcd]

Issue(s) Resolved

Closes knowledgefutures/pubpub#3179

(Looks like this issue was accidentally created in the pubpub/pubpub repo)

High-level Explanation of PR

This PR adds a button to the left side of form elements within the pub create form. Clicking the button toggles the disabled state for that field. By default all fields are enabled.

Disabled fields are omitted from the form when submitted. This means that submitting a form with all fields disabled will create a pub with no pub values.

Test Plan

1. Use the create pub button to create a pub.
2. Create pubs with various configurations of disabled and enabled fields. Values of disabled fields should not be present on newly created pubs.
3. The form's submit button should only be disabled when enabled buttons fail to validate. Invalid disabled fields should not be considered.
4. Update a pub. The buttons should not be visible on the update form.

Screenshots (if applicable)

The pub creation form with a disabled title field and invalid email field. The "Create Pub" button is disabled because of the enabled, invalid field.

The same pub creation form after disabling the invalid email field. The "Create Pub" button is now enabled because the invalid field was disabled.

The pub page of the newly created pub. Notice that the only field associated with the pub is "Member ID": the only enabled field on the form in the previous screenshot.

Notes

this looks good for the most part! just two things I found while playing around that may not be need to be addressed in this PR:

1. I can't create a pub with all disabled fields (I get a db error)

[16:15:08.231] ERROR: syntax error at or near ")"
    package: "core"
    err: {
      "type": "DatabaseError",
      "message": "syntax error at or near \")\"",
      "stack":

2. The create form doesn't seem to close after submitting (not sure if that was introduced in this PR)

uhh yeah not sure where this came from, ty!

This just coalesces the value to {} in the case the pub has no pub values.
