PDF export for time sheets

[as-op]

Ticket

https://community.openproject.org/projects/stream-time-and-costs/work_packages/59824

What are you trying to accomplish?

Export logged time as PDF time sheets

Screenshots

Button (in Figma this is in a drop down menu, should be done in a separate PR, here menu is out of scope)

File is created in the background worker

The PDF

What approach did you choose and why?

• Adapting from the XLS export for a cost query
• Reusing of existing PDF code (e.g. for the cover page)

Merge checklist

• Export skeleton PDF via the background worker and a button in the cost report view
• Don't navigate to .../job_statuses/xyz, use the "inline" progress dialog
• Apply styling
• Ellipse text in wp subject cell (missing prawn table support)
• Table splitting on page breaks with merged rows (missing prawn-table support for splitting)
• Use cost report query filter & data
• Use new start_time and time_zone for time on "time" column
• If an entry has its end time on a different day than the start date, it is indicated by a (+days), e.g. "23:00 - 04:00 (+1d)"
• Verify used values for header/footer/cover page vs wireframes
• Verify column widths with translations
• Added/updated tests
• Added/updated documentation in Lookbook (patterns, previews, etc)
• Tested major browsers (Chrome, Firefox, Edge, ...)

Great job 👏

I left some comments inline. We seem to work under the assumption that the Timesheet is the only PDF export we will ever generate for reports. I think it will be easy enough to add another parameter that tells us what type of PDF we want to generate, so that there is no need to do anything right now.

All in all, awesome work. Especially the edge case handling for weird PDF behavior.
