feat(epg): restructure progress panel template and actions

Refactor the EPG progress panel template to improve DOM structure and
action handling. Move the top-level panel wrapper and header markup so
the "dismiss all" button is rendered consistently when multiple imports
exist. Reorder imports list and per-item blocks so each import item
contains its own header, icon, url and dismiss button. Restore the
per-item dismiss button and adjust classes to distinguish between the
global dismiss-all and item-level dismiss actions.

These changes simplify markup nesting, fix button placement bugs, and
prepare the template for clearer styling and behavior of active and
queued import items.
