fix: glassmorphism actually visible + ESLint import/order

Glassmorphism root cause (from audit): the body-background useEffect
had `lotusTerminal && chatBackground === 'none' ? 'tactical'` as the
fallback guard — meaning the tactical grid only appeared when Lotus
Terminal mode was active. With default settings (TDS off, no chat
background chosen), the body got no background at all, so
backdrop-filter had a flat solid colour to blur — identical to unblurred.
Fix: drop the `lotusTerminal &&` guard so the tactical dot-grid is
always the fallback when chatBackground is 'none', regardless of theme.
Glassmorphism is now visible in all themes without any additional setup.

ESLint: RoomProfile.tsx had `../../../components/emoji-board` imported
before `matrix-js-sdk` violating import/order. Moved it after.
