This commit enhances the Patient class by adding several helper functions to improve access to organ data.

- Adds `getOrganSummary` and `getPatientSummary` to retrieve human-readable string summaries of organ vitals.
- Adds a templated function `getOrgan<T>` which allows for type-safe, direct access to specific organ objects. This enables calling organ-specific methods to retrieve raw data values (e.g., `heart->getHeartRate()`).

The example `main.cpp` has been updated to demonstrate the usage of all new functions.
