fix(rpc): populate dependencies in handleList response (#1300)

The daemon server's handleList was returning dependency counts but not
the actual dependency records. This complements PR #1296 which fixed
the direct CLI path.

Code paths now fixed:
- Direct (--no-daemon): cmd/bd/list.go (PR #1296)
- Daemon (default): internal/rpc/server_issues_epics.go (this PR)

Fixes bd-d240
