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

[tomerqodo]

Benchmark PR from qodo-benchmark#439

---

Note

Adds usable JSON object variables to advanced apps and improves schema handling.

• Exposes jsonObject type in type selector (non-basic apps) and removes unused jsonObjectWrap usage
• JSON Schema editor now accepts full schema (not just properties), preserves formatting, and clears json_schema when empty
• Validates schema on confirm (must be valid JSON with type: "object"); normalizes saved payload accordingly
• Updates jsonConfigPlaceHolder to a full object schema example
• Adds localized error messages for schema validation across all supported locales

Unused variable normalizedJsonSchema is dead code

Low Severity

The variable normalizedJsonSchema is computed but never used in the handleConfirm function. The actual saving logic uses payloadToSave instead, which computes the same logic inline. This leaves normalizedJsonSchema as dead code that adds confusion without providing value.
