feat: changed color of the app in settings

[AminTaheri23]

Description

I changed the colors in the dark theme and light theme from purple to blue. I know this seems small change, but I really didn't like the color. And not that fluent with React Native, and I wanted to participate in this project even if it's a small change.

Fixes no issues.

@AminTaheri23, thanks for sharing the screenshots. Could you please do the same for the light mode? Including the chat page?

I tested the new blue primary color, and I think it looks nice - specifically in the dark mode! but, I'm noticing that changing just the primary color may create some inconsistencies across the theme. I’m not a designer, but it might be worth considering updates to other related colors, such as primaryContainer, onPrimary, and any other shades or accents related?

For reference, this app uses React Native Paper, which uses Material Design 3 color system: https://callstack.github.io/react-native-paper/docs/guides/theming/#creating-dynamic-theme-colors

On that note, since we currently don’t have a Figma design, this could be a good opportunity to start one? What do you think about setting up an initial Figma file for this?

We have updated the theme and chosen blue as the secondary color.
