fix Project howver visibility (#3074)

## Issue Fixes #2962 - Improve the background color at hovering and MOST OF ALL for selected projects. ## Changes - Increased dark mode sidebar-accent background color contrast from 15.9% to 35% lightness - Updated both OKLch and HSL color formats for consistency - Selected items are now clearly distinguishable from unselected items ### Dark mode improvements: - OKLch: `oklch(0.35 0 0)` instead of `oklch(0.269 0 0)` - HSL: `240 5% 35%` instead of `240 3.7% 15.9%` This dramatically improves visibility for users with less acute vision, addressing the accessibility concern raised in the issue. ## Testing Added comprehensive E2E test to verify: - Selected sidebar items have visually distinct background colors - Hover states provide proper visual feedback - Good contrast between selected, unselected, and hover states  --- <a href="https://app.devin.ai/review/dyad-sh/dyad/pull/3074" target="_blank"> <picture> <source media="(prefers-color-scheme: dark)" srcset="https://static.devin.ai/assets/gh-open-in-devin-review-dark.svg?v=1"> <img src="https://static.devin.ai/assets/gh-open-in-devin-review-light.svg?v=1" alt="Open with Devin"> </picture> </a>
