This pull request focuses on updating the application's color palette to use a new set of brand colors (primarily switching from pink/blue gradients to magenta/cyan), while also making several UI/UX improvements and minor component refactors for better clarity and consistency. The most significant changes include color updates across all major components, a redesign of the model information panel, and improvements to the forecast status display.

Brand Color and UI Theme Updates:

• Updated all major UI elements, gradients, and accent colors from the previous pink/blue palette (e.g., #EB088A, #313CFF) to the new magenta/cyan palette (e.g., #E6007E, #48C0D9). This affects buttons, sliders, icons, charts, sidebars, status indicators, and loading animations for a more cohesive and modern look.

Component and Layout Improvements:

• Redesigned the ModelInfoPanel component to include an "About This Project" section, a technical paper link, and a simplified, more accessible list of input features. The available horizons section was removed for clarity. [1] [2] [3]
• Improved the ForecastStatusDisplay component for clearer live status indication, more user-friendly relative time formatting, and a streamlined layout. Removed some icons and refactored the code for simplicity and better UX. [1] [2]

Minor Usability and Style Tweaks:

• Adjusted the loading overlay to use fixed positioning and new brand gradients for better visual consistency.
• Updated sidebar and evaluation page gradients and hover states to match the new color scheme. [1] [2] [3] [4]
• Updated chart colors and slider highlights to use the new magenta/cyan theme. [1] [2] [3]

These changes collectively modernize the application's appearance, improve information clarity, and ensure a consistent, branded user experience.
