Refactor data management with browser and server storage sections

- Split LocalStorageManager into modular StorageManager component
- Create StorageSectionBrowser for localStorage/sessionStorage/cookies UI
- Create StorageSectionServer for server-side data management (mock)
- Extract ExportSection component from DataExport
- Add storage type icons (IconCookie, IconDatabase, IconTimer)
- Implement collapsible storage sections with visual indicators
- Add colored borders and gradients per storage type
- Display item counts and total size in section headers
- Improve delete button layout using CSS Grid
- Reduce DataExport from ~824 lines to focused component
