refactor(widgets): clean up animation timer and easing functions

Remove dead code and redundant blank lines, simplify timer interval selection, and ensure proper realization handling. This improves readability and prevents potential runtime issues.

New Features
-

Enhancements
- Refined timer interval calculation for clarity
- Consolidated easing function stubs for consistency

Bug Fixes
- Fixed missing realize handler connection in SlideRevealer
- Eliminated stray blank line that could affect indentation
