fix(ci): add missing eslint/prettier devDeps, fix tsconfig types

- Add eslint@^8.57.0, @headlamp-k8s/eslint-config@^0.6.0, prettier@^2.8.8
  as explicit devDependencies — without these the lint and format:check CI
  steps fail with "eslint: not found" / "prettier: not found"
- Remove vite/client and vite-plugin-svgr/client from tsconfig types — these
  are transitive deps that pnpm does not hoist; polaris plugin omits them too
  and tsc passes cleanly without them
- Update pnpm-lock.yaml to reflect new direct deps
