Node Callbacks: Call Enter/Leave at center of rail (.0 index)

- Unifies behavior of LZB and node callbacks (has_entered is obsoleted)
- Permits to set signal influence point on a TCB without issues
- Potentially solves bug which was happening when reversing a train at exactly index .5
(PS: Och_Noe will not like this :)

 To perform 2, it populates the train.path_speed table which is handled along with the path subsystem.
 This table is used in trainlogic.lua/train_step_b() and applied to the velocity calculations.
 
-Note: in contrast to node enter callbacks, which are called when the train passes the .5 index mark, LZB callbacks are executed on passing the .0 index mark!
-If an LZB checkpoint has speed 0, the train will still enter the node (the enter callback will be called), but will stop at the 0.9 index mark (for details, see SLOW_APPROACH in trainlogic.lua)
+Note: As of 2024-11-25, node enter callbacks as well as LZB callbacks are executed on passing the .0 index mark!
+If an LZB checkpoint has speed 0, it will stop at the 0.9 index mark (for details, see SLOW_APPROACH in trainlogic.lua) and will not enter the node.
+(previous behavior: node enter callback was called at .5 index mark)
 
 The start point for the LZB traverser (and thus the first node that will receive an approach callback) is floor(train.index) + 1. This means, once the LZB checkpoint callback has fired,
 this path node will not receive any further approach callbacks for the same approach situation
