feat(status): add per-entity sync counts from migration 027

Enhances sync status reporting to include granular per-entity counts
that were added in database migration 027. This provides better
visibility into what each sync run actually processed.

New fields in SyncRunInfo and robot mode JSON:
- issues_fetched / issues_ingested: issue sync counts
- mrs_fetched / mrs_ingested: merge request sync counts
- skipped_stale: entities skipped due to staleness
- docs_regenerated / docs_embedded: document pipeline counts
- warnings_count: non-fatal issues during sync

Robot mode optimization:
- Uses skip_serializing_if = "is_zero" to omit zero-value fields
- Reduces JSON payload size for typical sync runs
- Maintains backwards compatibility (fields are additive)

SQL query now reads all 8 new columns from sync_runs table,
with defensive unwrap_or(0) for NULL handling.
