This commit adds several micro-UX enhancements to `01_getting_started.py` and `02_logging.py` to provide a more intuitive and polished onboarding experience:

- 📏 Visual Separation: Replaced newline-based separation with `rich.rule.Rule` for "Next Step" guidance, creating a cleaner visual hierarchy.
- 🔄 Loading Feedback: Added `console.status` spinners to the mapping operations in both scripts to provide immediate visual feedback during processing.
- 📉 Reduced Log Noise: Reduced the demonstration logging loop in `02_logging.py` from 50 to 3 iterations, making the output easier to read without losing the pedagogical value.
- 📦 Improved Context: Added a "Fetched customer IDs" message to the logging demo for consistency with the first script.
- 🛡️ Type Compatibility: Removed explicit return type hints from Prefect flow entry points that return mapped results to resolve Mypy incompatibility issues with `PrefectFutureList`.
- 🧹 Consistency: Standardized messaging and styling across both tutorial scripts.

♿ Accessibility:
- Visual spinners provide feedback for long-running operations.
- Clearer visual structure aids readability for all users.
- Reduced output volume prevents terminal buffer overflow and improves experience for screen reader users by reducing cognitive load.
