Fix hot-reload SIGHUP trigger and accept row numbers in TUI prompts

- Send SIGHUP after config rewrite to reliably trigger engine hot-reload
  (inotify can miss events through Docker bind mounts)
- Allow secondary instance config updates even when primary is stopped
- TUI label prompts now accept row # in addition to label name (#33)
