Fix Phosphor icon class on GnButton/GnIconButton usages. ...

gnexus-ui-kit's iconNode() does not prepend the base `ph` class
when the icon string starts with `ph-`; it only keeps the string
as-is. All icon props must include the base class explicitly:
`icon="ph ph-sidebar"` instead of `icon="ph-sidebar"`.

Updated 15 icon bindings across 9 components.

Paginate session list loading

Improve content publishing UX

Go to WelcomeScreen when active session is deleted ...

Previously deleting the active session would load the first session from
the list. Now it calls clearSession() which resets currentId to null,
and showWelcome now triggers on currentId === null (not just empty list).
