The terminal's crew hand-overs screen opens a parked-twice issue with Enter, and `r` reads the list again #7415

Intent: the owner goes from "handed to the planner" to the issue itself in one key, without leaving the terminal.

Today src/tui/screens/crewhandover.ts lists the issues the crew parked twice and the last restore drill, but nothing in it can be selected or opened.

Done:

• [ ] A cursor moves over the parked rows (j/k, as other list screens do through common.ts). Enter on one pushes that repository's own issue screen at that number, the same screen the issues list opens. The drill row does nothing.
• [ ] r reads crewHandover again. The key hints say enter open · r refresh.
• [ ] The gate stays the same: only a forge admin who is a person sees rows. Anyone else sees nothing and opens nothing.
• [ ] A test (e.g. test/tui-crewhandover-open.test.ts) parks an issue twice, drives the screen and checks that Enter pushes that issue's screen. A non-admin gets no rows.

Files: src/tui/screens/crewhandover.ts, a new test.
