[hmr] Add IPython web interface page

[CNSeniorious000]

IPython provides convenient programmatic API to execute code cells with custom namespace support.

The project already has a console implementation at src/routes/console/ - we could easily add an /ipython page to support IPython's rich syntax (magic commands, auto-completion, etc.) on top of the existing infrastructure.

PROM-71 feat: Add IPython web interface page

[CNSeniorious000]

Actually, we could use run_ast_nodes to execute the code after applying packages/hmr/reactivity/hmr/exec_hack.
