fix(ui): prevent state dots from being clipped by physical notch (farouqaldori#44)

* fix(ui): prevent state dots from being clipped by physical notch

Apply closedContentWidth to frame modifiers so the closed notch expands
to accommodate session dots when multiple sessions are active. Also
expand the hit test rect in NotchViewController to match the expanded
content area, ensuring clicks on dots properly trigger the notch to open.

Fixes farouqaldori#37

* fix(ui): sync hit-test expansion padding with NotchView

Change expansionPadding from +40 to +38 to match the actual maximum
expansion width in NotchView.expansionWidth (base 20 + permission
indicator 18).
