fix: resolve all ESLint errors in client modules

Syntax-Error-1337 · claude · Syntax-Error-1337 · commit 2cb7caa3b87e · 2026-03-05T11:50:13.000+08:00
- Add proper TypeScript interfaces to replace 'any' types across cyber, monitor, and osint modules
- Fix React purity violation in CyberDataVisualization.tsx by computing Date.now() once per render
- Define type interfaces for RankedCountryRow, RankedAsnRow, RankedDomainRow, SpeedTableRow, BgpStats, AnomalyRow
- Define type interfaces for CyberDataRow, FeatureProperties, ACLEDEvent, ACLEDResponse
- Replace all 'any' type casts with proper TypeScript types for better type safety
- Remove unnecessary 'as any' casts in category selection handlers

This fixes CI workflow ESLint failures (21 errors resolved).
