fix(hermes-bots): keep the Cronjobs tile registered while it holds focus in Bot Mode

Clicking the Cronjobs tile shifts focus onto the tile itself, momentarily
dropping bot-chat workspace ownership — syncRoutinesPane then unregistered
the pane out from under the user's own click, with no way back. Keep the
tile while Bot Mode is on screen and the tile is the focused surface;
leaving Bot Mode still unregisters as designed. Live-verified.
