fix(media): 支持大尺寸图像响应并补齐迁移契约

- 为图像协议放宽 JSON 响应上限并显式处理读取与超限错误 - 合并基础模型与平台能力，避免运行时丢失分辨率和比例约束 - 固化稳定 Gemini 图像模型的能力、计价和 preview 兼容别名

+-- Callers use stable official Gemini IDs while provider bindings retain their
+-- upstream preview IDs. Capabilities and pricing are copied from the source
+-- EasyAI runtime contract instead of falling back to generic defaults.
