Dynamic SVG for current issue time entry state

Dynamically rendered SVG per issue that displays the time spent on an issue, to be added as footer to issue descriptions.
Image source should link to an API endpoint, so that the information can be displayed with up to date information without making unnecessary edits to the issue content itself.

The issue does not name any files, tests, entry points, or implementation technology. Start by locating the repository's existing application and API structure, then define how an endpoint can render current per-issue time data as an SVG; done means the issue footer can use a stable image URL that reflects updated time without editing the issue description.
