Add "Always" condition type to profiles

- Add AlwaysCondition model and evaluation (always returns true)
- Add condition type selector (Always/Application) in profile editor
- Show condition type pill on profile cards
- Fix misleading empty-conditions text (was "never activate", actually always active)
- Add i18n keys for Always condition (en + ru)
- Add CSS for condition type selector and description
