web-app-openproject: migrate from OpenProject 13 to 14

- updated base image from openproject/community:13 to openproject/openproject:14
- added dedicated migration task (db:migrate + schema cache clear)
- moved settings, ldap, and admin tasks to separate files
- adjusted docker-compose template to use OPENPROJECT_WEB_SERVICE / OPENPROJECT_SEEDER_SERVICE variables
- replaced postinstall.sh with precompile-assets.sh
- ensured depends_on uses variable-based service names
