fix(ui): 3 user-reported issues

1) MODAL OFF-SCREEN (Schema/AOI/Confirm dialogs)
DialogContent had `inset-0 w-full h-full` + `min-[880px]:inset-auto`
конфликтовал — inset-0 winning по CSS specificity, modal приклеивался
к левому краю viewport вместо центра. User screenshot показал Schema edit
выходящим за левую границу экрана.

Fix: remove inset-0 fullscreen pattern. Use simple centered modal —
left-1/2 top-1/2 -translate-x-1/2 -translate-y-1/2 + w-[95vw] max-h-[95vh]
overflow-y-auto. На mobile <880px max-w из size variant даёт ширину 95vw
(natural fit). На desktop max-w ограничивает до 440/560/720/880/920px.

2) LOGO 'ORDINIS MDM' С CIRCLE ICON (per redesign prototype)
Sidebar logo: 'ORDINIS' → circle icon (accent orbit ring + dot) +
'ORDINIS' bold + 'MDM' mute subtitle (Tektur). SVG inline — нет external
dep.

Collapsed mode: только circle icon, no text (uses Tektur ORDINIS dropped).

3) TIMELINE BUTTON LABEL
InfoPanel button 'Time-travel…' → 'Таймлайн' (per user feedback). Behaviour
не меняется — клик открывает picker. Inline таймлайн visualization
отложен (большой refactor, нужен product decision).

Verified:
  - Dialog modal центрируется на десктоп
  - Logo рендерится с svg + text
  - Tests: 116 pass
