chore(deps): update npm packages within declared ranges; reformat for prettier 3.9.4

npm update brought every package to the latest version its existing package.json
range allows (Angular tooling 22.0.2/22.0.4 -> 22.0.5, prettier 3.8.4 -> 3.9.4,
typescript-eslint 8.62.0 -> 8.62.1); package.json itself needed no range changes.

Auditing actual deprecation warnings (not just outdated versions) found nothing
further to fix: @angular/platform-browser-dynamic and @angular-devkit/build-angular
are deprecated by Angular but still required peer dependencies of the latest
published @storybook/angular (10.4.6 — peer range still `>=18.0.0 < 22.0.0`,
already why .npmrc sets legacy-peer-deps); jest-process-manager/expect-playwright
are transitive-only through @storybook/test-runner's latest stable (0.24.4). No
newer version of either Storybook package exists yet that drops them. The
remaining npm audit advisory (@babel/core, low severity) is the same
already-documented, deliberately-left issue in README.md (fixing it downgrades
Angular). Left package.json's overrides untouched.

The prettier bump alone changed formatting opinions on files this session didn't
otherwise touch (a stale markdown italics marker, a few object-literal wrap
points) — reformatted everything so `format:check` (part of CI) doesn't regress.
