fix(web): enable JSON_OBJECT type support in console UI

[tomerqodo]

Benchmark PR from agentic-review-benchmarks#2

---

Note

Enables configuring JSON object input variables directly in the config modal, including schema editing and validation.

• Adds jsonObject type to the type selector (non-basic apps)
• JSON Schema editor now handles/stores full schema (not just properties); placeholder updated to include type: object structure
• On save, optionally allows empty schema; validates schema is valid JSON and has type: "object"
• Removes wrapping via jsonObjectWrap; normalizes empty schema by omitting json_schema in payload
• Adds localized error strings for invalid schema across all supported locales

Python boolean True used instead of JavaScript true

High Severity

The handleJSONSchemaChange callback returns True (Python syntax) instead of true (JavaScript syntax). Since True is not defined in JavaScript/TypeScript, this will throw a ReferenceError at runtime when a user enters valid JSON in the schema editor, causing the JSON schema change handler to fail completely.
