chore: bump dompurify to 3.4.11 and expand VS Code tasks

- override dompurify to ^3.4.11 (fixes setConfig hook-pollution XSS advisory in the transitive swagger-ui-react dep)
- add frontend tasks (build, dev, gen, lint, test, typecheck, install, ncu) and go tasks (fmt, modernize, modernize -fix)
- add compound tasks: build:full (frontend + go) and check:all
