Feature Request: "Hide from Map" per-node toggle

Problem

Nodes with spoofed or unreliable GPS positions (e.g. received only via RF from a distant mesh) can clutter the map with markers at absurd locations. Currently the only options are:

• Ignore flag — hides the node from most views entirely (too aggressive)
• Position override — useful if you know the real location, but a workaround not a solution

Proposed Solution

Add a "Hide from Map" toggle in the node detail/edit view that:

• Suppresses the map marker for that node only
• Leaves the node fully visible in node lists, packet monitor, DMs, etc.
• Persists like other per-node overrides (label, ignore flag, position override)

Use Cases

• Node broadcasting a spoofed or wildly inaccurate GPS position
• Nodes received RF-only from far away with no meaningful location data
• Cleaning up map clutter without losing node visibility elsewhere

Notes

This is distinct from the ignore flag — users may still want to message or monitor a node, just not see a misleading pin on the map.
