feat: Client-side deployment, two-output graph, csv-validation

* Static client-side WASM-deployment (Closes #53)
  - Replaced Python/Jinja backend templates with fully static HTML.
  - Included light/dark theme toggle.
  - Added netlify.toml for Netlify build.
  - Added package.json for Netlify build triggers.
  - Added scripts/build_wasm.sh for installing dependencies,
    building SimDec wheel, converting Panel to Pyodide,
    and copying necessary files.
  - Needed to add data/stress.csv to panel/ for conversion to WASM.

* Fixed error handling with faulty CSV files (Closes #50)
  - Faulty files display error message
  - Faulty files keep buffering icon in UI

* Two-output graph (Closes #45)
  - Two-output graph is in a new function as in previous PR.
