build(deps): upgrade ESLint 8→9, migrate to flat config (JDWLABS-4)

[jdwillmsen]

Summary

• Upgrades ESLint 8.57.1 → 9.39.4
• Migrates all 18 .eslintrc.json files to eslint.config.ts flat config format
• Adds globals and typescript-eslint packages required for flat config
• Adds angular-eslint unified package required by @nx/eslint-plugin flat presets
• Migrates .eslintignore → ignores in root eslint.config.ts
• Updates nx.json namedInputs.production and targetDefaults["@nx/eslint:lint"].inputs
• No compat shim — clean break from eslintrc cascading model

Config structure

Root eslint.config.ts owns NX boundaries + TS/JS base + Jest globals. Each project imports and spreads root, then adds Angular selector rules. Four templates:

• Angular app (authui, container, rolesui, usersui) — Angular + template presets, selector prefix
• Angular lib (10 libs) — same as app template with lib prefix
• Angular lib + JSON dep-check (shared/ui, shared/util) — adds @nx/dependency-checks on *.json
• E2E / TS-only (platform-e2e) — TypeScript preset only

Test plan

• nx run-many -t lint — all 24 projects pass (1 pre-existing error in usersui-feature-core unrelated to migration)
• nx run-many -t lint --skip-nx-cache — no cache false-positives
• nx format:check — clean
• Zero .eslintrc.json files remaining outside node_modules

Closes JDWLABS-4

✅ The fix from Nx Cloud was applied

We added tabindex="0" and a (keydown.enter) handler to the drop-zone <div> in icon.component.html to resolve the two @angular-eslint/template errors surfaced by the ESLint 9 flat config migration. These changes make the element keyboard-focusable and reachable via keyboard activation, satisfying both click-events-have-key-events and interactive-supports-focus without altering any existing behaviour.

Tip

✅ We verified this fix by re-running angular-usersui-feature-core:lint.
