feat(web): show section icons in page headers across all pages

Add a typed icon prop to PageHeader that renders the section icon at
h-8 w-8 inside the heading, replacing the ad-hoc span wrapper used by
Channels and Routes. Migrate all 10 list pages to pass their section
icon, and add section icons to the 3 detail page headers (PacketDetail,
PacketGroupDetail, NodeDetail).

Normalize Channels/Routes title keys to the entities.* namespace
(used everywhere else) and add the missing entities.channels key to
nl.json ('Kanalen'). Visible text is unchanged.

Update PageHeader tests for the icon contract and add a focused icon
assertion to each affected page test.
