[FEATURE REQUEST] Configurable calendar lookahead window (CalendarDaysAhead)

[julianfj]

Description

Events returned should be ordered by start date so the frontend can render them grouped by day.

Use Case

A photo frame is a passive display — people glance at it while walking past. Showing only today's events means you miss anything happening tomorrow or later in the week. A configurable lookahead (e.g. 3–7 days) makes the calendar widget genuinely useful for day-to-day family or home use.

Details

• The calendar already supports recurring events via Ical.Net, so GetOccurrences(start, end) naturally handles them over any date range.
• A default of 0 (today only) keeps existing behaviour unchanged for users who don't set the option.

Pre-Submission Checklist

• This is a feature request and not a bug report

• I have checked for related issues and checked the documentation

I really like this idea, but I believe introducing a maxEventDisplayed constant or user configurable setting would be essential to avoid crowding smaller screens. So while the calendar would be able to fetch all events for 'x' number of days ahead, the frame should always display a limited number of event based on the user's screen size.

I would also further upgrade the get occurrences function to use the server's timezone in order to avoid returning events that already happened for today. Here's my take on it using lookaheaddays set to 2 (today, tomorrow, +1 day) and max event set to 9 (as that's what fits for my screen)
