refactor: simplify ticket form and SLA configuration handling

- Removed SLA configuration selection from the TicketForm component to streamline the ticket creation process.
- Updated the abrir-chamado route to eliminate unnecessary SLA loading logic and directly pass loading state to the TicketForm.
- Enhanced the central-chamados route to support SLA configurations by priority, allowing for better management of SLA settings.
- Introduced new mutations for SLA configuration management, including creation, updating, and deletion of SLA settings.
- Improved email templates for ticket notifications, ensuring better communication with users regarding ticket status and updates.
