App Switcher: Show Calendar only if its enabled

[db-ot]

Initial Checklist

• I understand this is a feature request and questions should be posted in the Community Discussions
• I searched issues and couldn’t find anything (or linked relevant results below)

Userstory:

As a user, I want to see the calendar entry in the Bento menu / App Switcher so that I don’t overlook it, but it should also be possible to hide it in specific cases where the calendar is disabled for the product.

Description:

• Calendar entry should be displayed by default
• Special cases (e.g., product instances where the calendar is disabled), the entry should be hidden
• Displaying must not depend solely on the backend status

Benefit:

• Users can easily find and access the calendar
• Reduces confusion or missing features
• Allows flexible control for different product instances

Acceptance Criteria:

• Display the calendar entry in the Bento menu and App Switcher by default
• Hidden entry in product instances where the calendar is disabled
• Showing entry does not depend on the backend service status, only on product configuration
• Introduce a new env variable FRONTEND_DISABLED_FEATURES which accepts an array of strings. those need to be popuplated to the web ui as capability.
• If this array contains radicale, the web ui doesn't render the app menu item Calendar and the account page sidebar entry Calendar

record FRONTEND_DISABLE_FEATURE

Why not FRONTEND_DISABLED_FEATURES? 🤔

DISABLED or DISABLE is arguable, but we expect a list, so FEATURES should be plural 🤔

FRONTEND_DISABLED_FEATURES is correct
