chore(cleanup): delete dead Vuexy views/ directory

src/views/ contained a single Vuexy-template file
(views/pages/authentication/AuthProvider.vue) with zero importers
in the repo. Vendored dead code from the original Vuexy template;
the §4.2 post-consolidation target layout drops views/ entirely.

Removed:
- apps/app/src/views/ (recursive)
- 'src/views/**' line from boundaries/ignore in .eslintrc.cjs

Closes TECH-DELETE-DEAD-VIEWS.
