fix(icons): replace remaining hand-rolled inline SVGs with Lucide

telegram-login: close X and lock icons (auth-gate icon reused across
telegram-login and cart - same 'log in required' concept, now the
same lock icon in both instead of two different hand-drawn shapes);
retry/refresh icon (QR expired/error states, was duplicated). Added
missing aria-label on the close button (had none).

catalog-empty-state, category, subcategories, item-detail: empty-state
illustrations (package/search/grid), add-to-cart icons, success/error
status icons, and thumbs up/down vote icons replaced. Rating stars
(item-detail, both product rating and per-review rating) now use one
Star icon with a color input and a .dx-star--filled CSS class for the
solid/outline toggle, instead of hand-toggling raw fill/stroke SVG
attributes - fixes the same rating-star pattern being drawn two
different ways (outline-only in the carousel earlier, fill-toggling
here).

Added color input to app-icon (was stroke-only via currentColor
before) and four more icons to the registry: refresh, thumbsUp/Down,
locate/mapPin (added earlier this session).

Also fixed the currency-dropdown chevron in language-selector that a
prior replace_all missed (same markup, different [class.rotated]
binding target).
