fix: migrate eslint configs from removed holocron export to bundles

[iamnewton]

Problem

All configs in this repo import holocron (and storybook, cypress) from the @theholocron/eslint-config root index:

import { cypress, holocron, storybook } from "@theholocron/eslint-config";

The root index only exports base, packageJson, and typescript. holocron is not exported from that entry point — this import resolves to undefined, meaning ESLint runs with no rules.

Fix

Migrate to the react-app bundle (which composes base + typescript + react + storybook + vitest + package-json) with cypress added via its subpath export:

import { reactApp } from "@theholocron/eslint-config/bundles/react-app";
import { cypress } from "@theholocron/eslint-config/cypress";

Also convert from .js to .ts config files to match the rest of the org.
