- right-click a profile square to rename or delete it, via shared
self-contained dialogs (also reused by the profiles page)
- switching or creating a profile now resets to a fresh new-session
draft so the prior session doesn't stay sticky across contexts
- deleting the profile you're currently in falls back to default
instead of stranding the gateway on a dead profile
- shared ConfirmDialog: Enter/Space confirm from anywhere in the dialog;
profile-delete and cron-delete both route through it
