Set Up `.streamlit` Folder and `secrets.toml` File for Secure Secrets Management

### **Summary**
This issue outlines the steps needed to set up a `.streamlit` folder with a `secrets.toml` file for securely managing secrets in our Streamlit application.

### **Steps to Complete**

1. **Create a `.streamlit` Folder:**
- In the root directory of the project, create a folder named `.streamlit`.

2. **Create a `secrets.toml` File:**
- Inside the newly created `.streamlit` folder, create a file named `secrets.toml`.
- This file will store our secrets in a structured and secure manner.

3. **Add Secrets to `secrets.toml`:**
- Add secrets to the `secrets.toml` file in the following format:

```toml
[database]
user = "your_username"
password = "your_password"
host = "your_host"
port = "your_port"

[api_keys]
google_maps = "your_google_maps_api_key"
sendgrid = "your_sendgrid_api_key"
```

- Example:
```toml
[database]
user = "admin"
password = "password123"
host = "localhost"
port = "5432"

[api_keys]
google_maps = "your_google_maps_api_key"
sendgrid = "your_sendgrid_api_key"
```

4. **Access Secrets in the Streamlit App:**
- Access the secrets in the Streamlit app using the `st.secrets` object:
```python
import streamlit as st

# Access database credentials
db_user = st.secrets["database"]["user"]
db_password = st.secrets["database"]["password"]
db_host = st.secrets["database"]["host"]
db_port = st.secrets["database"]["port"]

# Access API keys
google_maps_api_key = st.secrets["api_keys"]["google_maps"]
sendgrid_api_key = st.secrets["api_keys"]["sendgrid"]
```

5. **Update `.gitignore`:**
- Add `.streamlit/secrets.toml` to the `.gitignore` file to prevent secrets from being committed to version control:
```plaintext
# .gitignore
.streamlit/secrets.toml
```

6. **Deploying to Streamlit Cloud:**
- When deploying to Streamlit Cloud, set the secrets directly in the Streamlit Cloud interface under the "Secrets" section of the app's settings.

### **Additional Information**
By following these steps, we ensure that our secrets are securely managed and not exposed in version control.
