[JSWSERVER-8023] Use the startDate in version report calculations

Feedback Policy:

We collect Jira feedback from various sources, and we evaluate what we've collected when planning our product roadmap. To understand how this piece of feedback will be reviewed, see our Implementation of New Features Policy.

include the startDate for calculations in Version Report - both in the description on the top as well as on the timeline (i.e. timeline starts on the startDate)
versions without startDate use the previous calculations
if some stories were completed before the startDate, the "completed" line is adjusted at start, but are not included in the trendline calculations, nor do we display time before startDate.

Notes:

we might not be happy with the result and it may end up with the code staying on a branch + extra stories being created to improve it
