fix: Alpine.js x-data broken by inner double quotes + API list response crash

- Extract JSON data to <script> tags instead of tojson_attr in x-data attributes
- Remove literal " from CSS selector in x-data (meta[name=csrf-token])
- Move Alpine.js defer script after extra_js block in base.html
- Add isinstance(resp, dict) guard before .get("error") in measure.py and maker.py
