1. The previous color contrast calculation function was incorrect at least for the `#84b6eb` where it output low-contrast white instead of black. I've rewritten these functions now to accept hex colors and to match GitHub's calculation and to output pure white/black for maximum contrast. Before and after: <img width="94" alt="Screenshot 2024-04-02 at 01 53 46" src="https://github.com/go-gitea/gitea/assets/115237/00b39e15-a377-4458-95cf-ceec74b78228"><img width="90" alt="Screenshot 2024-04-02 at 01 51 30" src="https://github.com/go-gitea/gitea/assets/115237/1677067a-8d8f-47eb-82c0-76330deeb775"> 2. Fix project-related issues: - Expose the new `ContrastColor` function as template helper and use it for project cards, replacing the previous JS solution which eliminates a flash of wrong color on page load. - Fix a bug where if editing a project title, the counter would get lost. - Move `rgbToHex` function to color utils. @HesterG fyi --------- Co-authored-by: delvh <dev.lh@web.de> Co-authored-by: Giteabot <teabot@gitea.io>
