Log friction value when clicking a tile in the pathfinding data view (`P`)

The `P` view was implemented here: https://github.com/tibiamaps/tibia-map/commit/85fcd6b1699736101e0773e59d774d5c2b80c910

In this mode, when selecting a specific tile, it would be useful to `console.log` the tile's friction value (in addition to its coordinates).
