fix(docker): preserve pnpm symlink structure in web Dockerfiles

The production stage was copying node_modules to /app, but pnpm creates
symlinks pointing to ../../../../../node_modules/.pnpm/ (relative to the
app's node_modules location). When the directory structure changed, these
symlinks broke, causing "Cannot find package" errors.

Fix:
- Keep same directory structure in production (/app/apps/*/apps/web)
- Copy the root .pnpm store that symlinks point to
- Copy the app's node_modules which contains the symlinks

Affected apps: todo, manacore, chat, calendar, clock
