feat: update agenda references to use ULTICAL_APP_NAME and enhance AI usage sections

- Replaced hardcoded "Agenda" labels with dynamic ULTICAL_APP_NAME in various components for consistency.
- Introduced new AiUsageSection and CompteAiUsageSection components to track AI usage and costs.
- Updated settings and metadata to reflect changes in AI cost policies and usage limits.
- Enhanced user interface elements for better accessibility and user experience across admin settings.
