[Feature]:Add option to set calendar view as default

### Short summary Calendar first ### Detailed description Hi! I love your lunar-phase-card! Would it be possible to add a YAML configuration option to set the calendar view as the default view instead of the horizon view? Something like: ```yaml type: custom:lunar-phase-card entity: sensor.moon_phase default_view: calendar # or: base, horizon, calendar ``` This would be very helpful for users who primarily want to see the monthly moon phases calendar.(or just me ;-) Thank you for considering this feature request and thanks for your work ! jeybe ### Examples 🖼️ _No response_ ### Additional context 🗒️ _No response_
