Add boolean field support

[doneill]

Adds support for #36

Proposed Changes

types.ts

• V2BaseProperty.type
  • added boolean to the union
• V2UIField.type
  • added BOOLEAN to the union

generateUISchema.ts

• Added BOOLEAN to supportedFieldTypes in the validator so boolean fields aren't rejected

utils.ts

• Added case BOOLEAN to createControl's switch
  • sets format: boolean so JSONForms renders it as a toggle/checkbox; description and label are handled by the existing generic logic below the switch

v2.test.ts

• Added a BOOLEAN field type describe block with three tests: control output shape, description forwarding, and
  deprecated field suppression

Implementation Test

In React Native client app, e.g. EarthRanger

- yarn remove @earthranger/react-native-jsonforms-formatter
- yarn add @earthranger/react-native-jsonforms-formatter@2.0.0-beta.25
