fix: 🐛 minimal react 19 and rsc support

[punkbit]

Why?

TLDR; Click-UI fails to install, run or build on major React-like libraries, e.g. HyperDX, Nextjs, Vitejs latest. The PR provides a minimal set of changes to unblock the team.

The current/latest versions of click-ui, such as https://www.npmjs.com/package/@clickhouse/click-ui/v/0.0.250, break on the latest of Nextjs, Vitejs, any React >= 19 or RSC enabled builds. To mitigate it, this initial PR provides the minimal setup required for it to work in such environments, e.g. when installing the package, it should run in dev and build processes. It does NOT try to modify, replace, introduce or change breaking changes. At the time of writing, the library requires a browser runtime, being client-only. Separately, there'll be other PR to address other related concerns and expand on this initial PR, e.g. none interactive components shall render server-side.

A version is provided as:

https://www.npmjs.com/package/@clickhouse/click-ui/v/0.0.251-rc.17

npm i @clickhouse/click-ui@0.0.251-rc.17

How?

• Make styled-components, as an external dependency
• Opens brief support for hosting on React v19 projects retroactively
• Declares as client library at entry point, preventing nested/subtree-related issues
• Resolve some type issues

Demo?

@kunalpanchal are you able to find some time in your AM to test this?

Tested in HyperDX here, and it works as expected.

LGTM! 🎉

Apart from the minor type error mentioned above, everything else looks and works fine on control-plane.

Just to avoid confusion, this is not shipping a type error! The change is a requirement due to a small deprecation in the context menu as described in the changeset here https://github.com/ClickHouse/click-ui/pull/756/changes#diff-801534275d6fc19b60543371f1055838e7d60942fa4005c3ab1623293e10fb7fR24
