feat: F016 future availability workspace

2-panel workspace at /supply/future-availability: filterable signal list with FutureSignalCard (type/sensitivity/review badges + mandatory disclaimer) and collapsible detail panel with full evidence, review workflow (IN_REVIEW→APPROVED/REJECTED), shortlist action, and review task creation.
