Add new Mealie meal plan types to calendar and services

[andrew-codechimp]

Proposed change

Mealie 3.7 introduced new meal plan types. This PR adds support for these with backward compatibility with older versions.

Calendar - checks the Mealie version and only creates calendar entities supported by the version.

Services - Adds the meal plan types to the two services that add meals, with a version check and a service validation error being raised if trying to use the new meal plan types with older versions.

Mealie has nightly versions, which are un-versioned, we already have a warning that nightly is not supported and assume that they are running the latest version if this is the case.

Pull request overview

This PR adds support for three new meal plan types (dessert, drink, snack) introduced in Mealie 3.7, while maintaining backward compatibility with earlier versions. The implementation includes version checking to conditionally create calendar entities and validate service calls based on the Mealie server version.

Key Changes

• Version-based validation ensures new meal plan types are only used with Mealie 3.7+
• Calendar entities are dynamically created based on server version
• Service calls validate meal plan types against the server version
