feat: add dedicated hex monitor component for hex value display}
- Add HexMonitorComponent (Angular) and HexMonitor (React) with proper hex dump layout: address column, hex bytes, and ASCII representation - Include horizontal scrollbar sync via ResizeObserver for wide content - Show truncation indicator when value exceeds display limit - Remove inline hex formatting from formatValue() in key-type-base.ts (both Angular and React) since hex rendering now uses dedicated component - Update all key type components (hash, list, set, stream, string, zset) to conditionally render HexMonitor when valueFormat is 'hex' - Conditionally toggle p3xr-pre class and overflow style based on format - Bump version from 2026.4.423 to 2026.4.426
