Combines ConversationThumbnail with a quote-styled summary, truncated
meta line, and up to three tag chips (the rest collapsed into "+N").
The colored left border tells a reader at a glance whether this
letter left or entered the perspective person's mailbox — replacing
the previous status dot + script-type icons that were too busy for
the list view. Relative-year label ("vor 76 Jahren") is derived from
documentDate so the list carries temporal context without a full
date column.
Rendering rules:
- title falls back to originalFilename when empty
- summary uses a text expression, never {@html}, so inline markup
in the summary field is escaped (XSS regression test locks this)
- focus-visible outline + focus-within hover keep keyboard-only
users in sync with mouse hover feedback
- aria-label always pairs title with the formatted date so screen
readers hear both identifiers
