chore: upgrade dependencies and resolve security vulnerabilities

- Upgraded non-Expo dependencies to their latest compatible versions and aligned Expo modules with SDK 54 recommendations.
- Pinned `react-dom` to `19.1.0` to resolve a peer dependency conflict with `react@19.1.0`.
- Resolved npm audit security vulnerabilities in `postcss` and `markdown-it` by adding npm overrides.
- Verified all packages installed without vulnerabilities and ensured linter output is error-free.
