Issues with SDFG viewer

This issue refers to 2 issues I have recently encountered with the SDFG viewer.
**Issue 1**
Search doesn't work in the `sdfv` provided by `uv pip install --prerelease allow dace` and the images of some UI elements doesn't work

**Issue 2**
The VSCode plugin of DaCe cannot visualize certain (large-ish) SDFGs like the one attached to the issue. The same SDFG though gets visualized by the `sdfv` locally (with the above issue) and https://spcl.github.io/dace-webclient/

[program.sdfgz.zip](https://github.com/user-attachments/files/30125397/program.sdfgz.zip)

Start by reproducing the two reports with the `sdfv` installed through the shown `uv pip install --prerelease allow dace` command and with the supplied `program.sdfgz` in the VSCode plugin. Compare the local viewer with the DaCe webclient, focusing on search, UI images, and rendering of the larger SDFG. Done means the affected UI elements work and the VSCode plugin can visualize the supplied SDFG.
