UX Refinement, Sticky Controls & Anti-Detection Safety (#275)

* added smart selection, data export (CSV/JSON), and HD profile previews

- Added Smart Select buttons (Verified, Private, No-Pic).
- Added CSV/JSON export functionality.
- Implemented HD avatar preview on hover.
- Refactored selection logic for ES5 compatibility.
- Fixed TypeScript linting errors in icon components.

* Add whitelist UI, anti-detection & persistence

Introduce whitelist management and UX improvements: add per-row star (★) whitelist button, make UNFOLLOW action sticky in the sidebar, and persist whitelist + scan timing settings to localStorage. Implement anti-detection timing (random micro-pauses and randomized sleep cycles) to better mimic human behavior. Refactor sidebar layout for higher density, update scan summary to a 3-column grid, and apply glassmorphism/scrollbar visual tweaks. Updates touch core UI components, whitelist manager, styles, main app entry and embedded public script, and document changes in the changelog.
