[CONFIGURATOR] Next iteration issues

[Nico-Sanchez]

• Improve/change new version form.
• Characters get skills from previous version, not new one (you can check this by editing a character skill).
• Fix weird schema_to_map conversion to create new version.
• Autobattler skills don't have a version.
• Versions missing "soft-delete" behavior.
• Fix vertices in skill_mechanics_inputs
• Add every assoc as required in Version schema, this will lead to a seeds reorganization.
• Fix consumable items effect form. Now they don't allow submission if they don't have an effect name.
