[Feature]: Make the moon picture available

### Short summary I'm showing the card in a pop-up. I'm opening the pop-up from clicking on a Mushroom Template Badge. I wish the badge used the moon picture ### Detailed description I see you're using https://cdn.jsdelivr.net/gh/ngocjohn/lunar-phase-card@1.4.1/static/moon_pic/{phase}_moon.webp with 0 =< phase =< 30 And I could use them too with templating but the standard Moon sensor in HA doesn't expose the age of the moon. I could download an integration just for that but that seems a lot for only one feature. ...could the **card** make it available somewhere on the system (with a link in a text file or something)? Or is that something only integrations can do? ### Examples 🖼️ <img width="154" height="47" alt="Image" src="https://github.com/user-attachments/assets/8bbe2bdf-ef8c-48d7-817b-41fd9c465e6e" /> <img width="157" height="49" alt="Image" src="https://github.com/user-attachments/assets/61eb2fd8-9cba-4761-9753-4345d3f9fb50" />
