chore(deps): update @types/node version across multiple packages

- Upgraded @types/node from version ^18.19.104 to ^20.16.0 in package.json files for apps/api, apps/dokploy, apps/schedules, and packages/server.
- Adjusted pnpm-lock.yaml to reflect the updated @types/node version across all relevant dependencies.
- Added a new setup file for mock database interactions in the dokploy app to enhance testing capabilities.
