Rename profiles to automations across backend and frontend

Rename the "profiles" entity to "automations" throughout the entire
codebase for clarity. Updates Python models, storage, API routes/schemas,
engine, frontend JS modules, HTML templates, CSS classes, i18n keys
(en/ru/zh), dashboard, tutorials, and command palette.
