fix: Parse wizard_plan from edit_fields_parsed structure

Problem:
- wizard_plan comes in nested structure: edit_fields_parsed.wizard_plan_parsed
- Old SQL looked for wizard_plan at root level (partial.p->'wizard_plan')
- Result: wizard_plan was always NULL even though it existed in payload

Solution:
- Updated wizard_plan_parsed CTE to check multiple locations:
  1. edit_fields_parsed.wizard_plan_parsed (already parsed object) ✅
  2. edit_fields_raw.body.wizard_plan (escaped JSON string)
  3. Root level wizard_plan (backward compatibility)
  4. Database fallback (if not in payload)

- Updated wizard_answers_parsed CTE:
  1. edit_fields_raw.body.wizard_answers (string) ✅
  2. edit_fields_parsed.body.wizard_answers (string)
  3. Root level (backward compatibility)

- Updated session_id, unified_id, contact_id, phone extraction:
  COALESCE() checks edit_fields_parsed.body and edit_fields_raw.body

Input structure from n8n workflow form_get:
{
  "payload_partial_json": {
    "edit_fields_parsed": {
      "wizard_plan_parsed": {...},  ← TARGET
      "body": {
        "session_id": "sess_xxx",  ← ALSO HERE
        "unified_id": "usr_xxx",
        "wizard_answers": "{...}"
      }
    }
  }
}

Now: wizard_plan preserves correctly when uploading files ✅
