feat: Refactor Docker configurations and server logic

Removes redundant Dockerfiles and configurations, consolidating them into a single set. Updates server logic for handling expense shares and notice targets to ensure correct parsing and deletion of associated records. Introduces a check for family association in the user's profile to prevent rendering payment options when a family is not assigned.
