Update Step1GraphBuild.vue and Step2EnvSetup.vue with API endpoint notes and enhanced styling

- Added API endpoint notes for simulation creation and preparation in Step1GraphBuild.vue and Step2EnvSetup.vue respectively.
- Updated badge styling for processing state to improve visibility.
- Enhanced the narrative box layout and added a custom checkbox for configuring simulation rounds in Step2EnvSetup.vue.
- Introduced a new section for simulation rounds configuration, including user-defined options and estimated time for completion.
