Redmine

Merge a duplicate source issue/ticket into an existing one. Built for the dispatch workflow where an incoming mail without [#issue-number] in the subject, spawns a second issue about the same topic.

When merging a source issue → target issue:

1. One journal entry is added to the target issue containing the source description and (optionally) all of the source's notes. The first line is a freely editable header (default from the settings, e.g. Eintrag/Merge aus Duplikat #123). The entry is rendered inside a configurable CSS box.
2. Attachments are moved from the duplicate to the target issue (only the database foreign key changes; the files on disk stay untouched).
3. A "duplicates" relation is created between the duplicate and the target.
4. The duplicate is closed (not deleted) and gets a back-reference note, so you can always look it up later.

No schema migration, no manual SQL, no changes to Redmine core files. Only the regular models are used.
