1.2.0 Single Template Input

Frontend

• Redesign to a single template input. The multi-template editor is hidden and can be activated with the parameter mailgen_multi_templates_enabled
• Pass assigned columns to the backend for notification preview and data submission
• Minor style enhancement in email preview
• Minor: add more spacing between the explanation text and the subject
• Target groups: add select all/none buttons
• Separate function for converting data to table

Backend

• Allow single template input and pass to mailgen
• Do not send data to the redis queue if validation/submission with bots is active (would be a double-submit)
• Refactor format_spec creation, more checks/sanitation
• Template preview: use first line of data instead of fully relying on example data, use the first line of input data if available
• Use assigned columns as default table format: the columns assigned by the user in the frontend are used as default table format for mailgen
• Compatibility changes on deprecated pkg_resources / importlib replacement, make it compatible on both Ubuntu 20.04 and 22.04, update tests and GitHub Workflows

Documentation

• Add section about the behaviour of the Frontend's "Submit/Validate with Bots" parameter
