feat: undo mistaken moves, numbered pagination, and quieter Kanban messages

Moves: an order can go back one stage (BACK in app/runtime.py) with an
internal reason, flagged in the history as movements.back. The customer is
not notified and approved finals stay; "production started" and "ready" are
now enqueued once per order, so undoing and redoing a move sends nothing
twice. Dragging only goes forward and highlights the allowed column. Move
errors are in Portuguese.

Lists: the send log, payments (open, resolved as history, all) and quotes
are paged on the server with a total, 20 rows by default (10/20/50/100),
first/previous/page/next/last. The send log filters by destination, status,
event and order. Older finished orders load on demand. The board no longer
carries the send log or payment rows, only the open-payment count.

Kanban: Pagamentos and Integrações are separate tabs; messages are brief,
bottom notifications that clear themselves; wording is shorter.

Full CI integration sequence passes locally, with new checks for undo, paging
and filters.
