📄 Description

This PR updates how Vikunja stores tasks in its CalDAV server. Specifically, it maps RRULE:FREQ=SECONDLY to the appropriate DAILY or WEEKLY interval frequency where possible.

Why?

Vikunja currently stores all CalDAV recurring tasks with FREQ=SECONDLY in its RRULE field unless the "Repeat mode" is set to "Monthly". This is permissible and logical as tasks recurring daily or weekly can be represented as recurring every X seconds. Unfortunately, iOS does not support CalDAV tasks with a SECONDLY interval frequency.

If you try and connect to Vikunja CalDAV from iOS and create, for example, a daily recurring task, iOS Reminders will break and refuse to show subsequent updates to the task list.

Please see this issue to understand my debugging process.
