fix(cli): single source of truth for manifest schema

[matthewvolk]

What/Why?

Mistakenly, the applyIntegrations utility function was not updated to reflect the new shape of the integration manifest.json file, so it failed during consumption. This PR defines a single Manifest schema with zod and uses it as a single source of truth for all references to manifest throughout the CLI.

Testing

Testing built CLI:
