Feat add llm tag annotation

[laqua-stack]

This adds the possiblity to define json templates for [llm-tag](https://github.com/pwoznicki/llm-tag/) that will be prefilled from the content of the report. In addition, multiple users can be created, where the default is named 'default'. The stored annotations can be reviewed. By default either the user's last annotation or the llm-tag annotation is loaded (depending on the checkbox). closes #34. closes #19 (cf. also [llm-tag](https://github.com/pwoznicki/llm-tag/) for the creation of templates). closes #7. closes #13.

TODOs (can be opened as separate issues if needed):

• [ ] Update documentation for webapp
• [ ] Update documentation to start the guidance REST Api/ Load llm into gpu
• [ ] Update documentation to preannotate reports and store them into postgres (scripts)

@AmarHek I changed this version to serve the webapp using docker. Could you give it a look?
