fix: detect power cables by termination type and move toggle into topology card

Power-cable detection previously relied on cable.type, which is usually
unset for power patch cables (e.g. PDU-to-PDU), so they never got the
distinct color. Power cables are now also detected by termination
component type (PowerPort/PowerOutlet/PowerFeed).

Wireless/power display is now toggled client-side via checkboxes in the
Kabeltopologie card header (before the SVG/PNG/draw.io export buttons)
instead of a server round-trip through the top filter form, so toggling
is instant and affects exports too.

Bump plugin version to 4.5.2.
