feat(ui): add CMPA agent dashboard link to header

Adds a "ניהול סוכנים" link on the opposite side of the "עוזר משפטי"
title in the app shell header. Opens the Paperclip CMPA dashboard
(pc.nautilus.marcusgroup.org/CMPA/dashboard) in a new tab for quick
cross-tool navigation between the legal-ai workspace and agent ops.
