Update calendar card to allow variable height, better multi-day event support

[hoverduck]

Proposed change

This allows the Calendar card to behave the same way as the Calendar panel from the sidebar, where multi-day events are displayed in blocks spanning the calendar rather than on the start date only.

This revisits a design decision made in #14660, where the behavior was allowed to differentiate. The argument in that PR was that the Calendar Card was too cramped to effectively display the multi-day events, so I've also added an option to choose the card's height.

Hi @hoverduck

Can you please split this up in 2 PRs one for height and one for all-day

Setting a height in px is very specific and I would keep it as a yaml option only.

Your editor options labels are plain text, they need to be translated.

I know you havn't changed anything in ha-full-calendar but the full day events doesn't work well with my real data. When it's over multiple rows it shows in the first row only. When the title is wider then the cell it just overlaps.
At this state this can't be merged.
