fix: resolve Docker build failure by optimizing configuration and prisma signal handling

- Added .dockerignore to prevent build poisoning from local artifacts.
- Updated Dockerfile with stable Bun version, memory limits, and missing config files.
- Refined prisma.ts signal handlers to avoid process termination during Next.js build phases.
- Synchronized eslint-config-next with Next.js version.
