chore: fix security vulnerabilities by updating nextjs and prisma

[inflamously]

This PR addresses several issues encountered during the build, development and usage of the frontend ui.

The primary goals were to resolve npm audit issues and prisma-related errors to clean up build warnings.

• Prisma upgrade: prisma and @prisma/client dependencies have been upgrade from 6.3.1 to 6.4.1.
• Deprecated Next.js Config Removal: The deprecated devIndicators configuration has been removed from next.config.ts to eliminate build warnings.
• Next.js Update: The next dependency has been updated from 15.1.7 to 15.5.6.
