Calendar menu visible by default even without Radicale deployed

[michaelstingl]

Problem

support_radicale capability defaults to true, showing Calendar menu even when Radicale is not deployed.

Users see: "The calendar is not yet configured on your system, in order to learn how to enable click here" - but regular users cannot configure server-side services.

Current Behavior

• docker-compose.yml does not map FRONTEND_DISABLE_RADICALE
• Backend default: disable_radicale: false → Calendar visible
• Without radicale/radicale.yml in COMPOSE_FILE → broken UX

Expected Behavior

Calendar menu should only appear when Radicale is actually deployed.

Suggested Fix

docker-compose.yml:

FRONTEND_DISABLE_RADICALE: "${FRONTEND_DISABLE_RADICALE:-true}"

radicale/radicale.yml:

services:
  opencloud:
    environment:
      FRONTEND_DISABLE_RADICALE: "false"

This way:

• Default (no Radicale): Calendar hidden
• With radicale.yml: Calendar visible and functional
