cli: fix enable_thinking and chat_template_kwargs not being used

PR ggml-org#18675 (Autoparser refactor) accidentally replaced
`chat_params.enable_thinking` with a call to
`common_chat_templates_support_enable_thinking()`, which only checks
if the template supports thinking — ignoring --reasoning-budget and
--chat-template-kwargs entirely.

This restores the use of `chat_params.enable_thinking` (which already
incorporates reasoning_budget), adds the missing chat_template_kwargs
passthrough, and parses the enable_thinking kwarg to keep
inputs.enable_thinking consistent with what the template receives
(matching server-common.cpp behavior).

Fixes ggml-org#20182
