ui: bulk-edit edits cells in place instead of a stacked per-row form

"Изменить" previously replaced each camera row with a vertical .cam-edit-grid
form inside one colspan cell — effectively a different table. Now bulk edit
keeps the same columns and turns the cells into compact inline inputs:
Камера→name, IP→ip, Потоки→main/sub, Вкл/Запись toggles, Хранилище select,
and the Статус column becomes Логин/Пароль (header swaps via data-bulk-label).
Live per-row onchange is suppressed while bulk is active (changes collected
until Сохранить). Inputs are compact (22px) so row height stays dense.

VERSION 0.0.131.
