fix(docker): Fix module resolution and healthcheck syntax

Issues fixed:
1. Module not found: Added missing copy of apps/{api,web}/node_modules
   which contains pnpm symlinks to the root node_modules

2. Healthcheck syntax: Fixed broken quoting from prettier reformatting
   Changed to CMD-SHELL with proper escaping

3. Removed obsolete version: "3.9" from docker-compose.yml

The apps need their own node_modules directories because pnpm uses
symlinks that point from apps/*/node_modules to node_modules/.pnpm/*
