feat(ui): optimize node parameter defaults and text handling

* Restrict default parameter enablement to the first valid parameter of each node.
* Ensure `text` and `tex_strings` parameters are always enabled and unescaped by default.
* Force `text` and `tex_strings` to use string input boxes, overriding numeric type detection.
* Update LaTeX helper to apply unescaped formatting when injecting code into nodes.
