What changed and why

Clicking the parked-car marker opened the parking panel and also dropped the grey pin and place card of a plain map click. MapLibre mounts DOM markers inside the map's event container, so a marker click also fires a map click at that point. Several markers left it unclaimed:

• the location dot, which also dropped a pin and closed the place panel
• the arrival parking markers
• route waypoints: a tap filled the next empty waypoint with the waypoint's own position
• the selected route pill
• the dropped pin itself: a tap re-dropped it a pin's height higher

Before	After

Every marker now handles clicks through bindMapMarkerActivation. It claims the click through the existing map click ownership with a new marker owner. Every map click handler already ignores owned clicks.

• Claimed, not stopped. The click still reaches listeners outside the map, so a marker click now closes the right-click menu. That includes the pins and pills that used to stop propagation.
• Pickers keep priority. A click an active picker owns stays the picker's: parking reposition, crowd report, measurement or travel time.
• Action-less pins stay see-through, so a hover pin over a feature still lets that feature take the click.

A static test requires each file that creates a marker to bind it, apart from three listed pass-through markers. It also requires every map click handler to consult ownership. The integration system docs describe the rule.

Verification

• Local checks: pnpm check-types (web) passes, and Biome passes in the pre-commit hook.
• Full Vitest: 24,118 passed and 1 failed. The failure is a load-sensitive timing budget in road-conditions dedupe (5.4 s against 5 s), code this PR doesn't touch. It passes on its own.
• New tests: they fail against main's marker code and pass with this change.
• Real app, using next dev against the production API with a parked car in local storage:
  • clicking the car opens only the parking panel
  • a marker click closes an open context menu
  • "Change location" still takes a point on the badge
• Not run by hand: the location dot, arrival parking, waypoints and route pills (tests and the static check cover them), and touch devices.
