Xml translation and bugfixes

[Daan0709]

• Fixed issue where 'succes' handletypes could be duplicated
• Fixed issue where 'can drop here' text would linger on elements if the dragged element was dropped onto the canvas
• Improved xml to flow translation cases, such as issues with edge generations

All adapters must follow the rules below when generating edges (The links between nodes):

1. Explicit Forward Edges

• Every <Forward> element must always generate an edge.
• The edge connects the current node (source) to the target specified in the <Forward> element.
• The type and index of the source handle should reflect the order of the forwards.

2. Implicit Pipeline Edges

• For nodes within the <Pipeline>, edges are generated top-to-bottom to simulate the natural flow.
• Skip creating an implicit edge in the following cases:
  1. The current node has one or more <Forward> elements that target any other pipeline node.
  2. The current node has a <Forward> element targeting an exit node with state="SUCCESS".
• Implicit edges ensure that pipeline execution flows correctly even if explicit forwards are missing, but never override explicit logic.

3. Implicit Success Exit Edge

• If there is an exit node with state="SUCCESS":
  • And the last node in the pipeline does not already forward to any exit,
  • Then automatically generate an implicit edge from that last node to the success exit.
• This guarantees that successful pipeline completions are always connected to the success exit.

Closes #180 , Closes #181, Closes #140

Nog wat feedback

[Daan0709]

findSuccessExit() maakt nu gebruik van isSuccessExit(), hierdoor is er een stuk minder gedupliceerde code en is de definitie van wat nou een 'success' exit is constant. Hierdoor hoeft ook geen const aangemaakt te worden, aangezien 'success' nog maar één keer voorkomt in de code.
