Piece 2 of the MVP (#1503). A one-line reply box and Send in the detail
of rows with a live registration; POST /api/reply runs
tools/tmux/agent-send.sh -s <session> -S <host>:control-board
[-L <socket>] -m <text> once for one seat and returns the exit code,
stdout and stderr. The page shows delivered or failed with the tool's
stderr; other rows say "reply needs a registered seat". No send-keys,
queue, retries, history or broadcast; packages/seat and agent-send.sh
untouched. Every message ends with a fixed trailer telling the seat to
answer in its own session (Jason's refinement after the first Gate C
exchange; the board has no pane). Board suite 98/98.
