Render a Dolly logo badge next to staff usernames sitewide. Staff DIDs are configured via STAFF_DIDS (comma-separated env var). New `fragments/dolly/badge` template renders the badge inline. Also strips Inkscape metadata bloat from dolly logo SVG, and fixes timeline templates that were passing resolved handles instead of DIDs to picHandleLink. Signed-off-by: eti <eti@eti.tf>
