chat : add new template for DeepSeek V4 Flash 0731 (#26398)

• common/chat: update DeepSeek V4 templates

Align the DeepSeek V4 templates with the official encoders while keeping parser behavior out of this change.

• Default drop_thinking for DeepSeek V4 history so prior thinking is omitted unless preserve_reasoning is requested or tools are present.
• Add structured output response-format instructions to the V4 templates and pass the schema into template rendering.
• Add a separate Flash 0731 template for the updated high and max reasoning effort mapping.
• Cover reasoning effort, drop_thinking, structured output prompts, preserved reasoning, continuations, and empty tool arguments in template rendering tests.
