Remove pre-existing dead code surfaced by the automations removal sweep

[paulocastellano]

While removing the automations module (#333) an orphan sweep of resources/js and app/ turned up dead code that predates automations. It is out of scope for that PR and tracked here so it is not lost.

Everything below has zero importers/references on main (verified by grepping for the import path or class name across resources/js, app, config, routes, tests, resources/views).

Frontend components and layouts (starter kit, Jan 2026)

• resources/js/components/AlertError.vue
• resources/js/components/AppContent.vue
• resources/js/components/AppShell.vue
• resources/js/components/Breadcrumbs.vue
• resources/js/components/Heading.vue
• resources/js/components/Icon.vue
• resources/js/components/NavFooter.vue
• resources/js/components/PlaceholderPattern.vue
• resources/js/components/UserInfo.vue
• resources/js/components/WorkspaceSwitcher.vue
• resources/js/components/posts/previews/LinkCard.vue (Bluesky link card preview, Jul 2026)
• resources/js/composables/useDateMaska.ts
• resources/js/layouts/GuestLayout.vue
• resources/js/layouts/auth/AuthCardLayout.vue
• resources/js/layouts/auth/AuthSimpleLayout.vue

components/ui/* directories with no importer outside ui/

• alert-dialog, aspect-ratio, button-group, carousel, context-menu, drawer, empty, hover-card, input-group, input-otp, kbd, native-select, navigation-menu, progress, radio-group, range-calendar, resizable, scroll-area, sheet, tags-input
• After removing them, re-check package.json for packages that only they used (embla-carousel-vue, vue-input-otp, vaul-vue, maska are candidates).

PHP

• app/Concerns/PasswordValidationRules.php
• app/Enums/Ai/Orientation.php
• app/Exceptions/Ai/QuotaExhaustedException.php

npm

• axios: no import anywhere in resources/js. Inertia v3 no longer depends on it.

Notes

• The import/order eslint errors on main (32 at the time of writing) are auto-fixed by npm run lint in CI, but each PR that runs lint locally picks up unrelated import reorders. Worth one dedicated lint-fix commit.
