Not correct length of Multi-Tailed and Single arrows for reactions with atoms after loading from RDF or Layout actions

[ivanmaslow]

Steps to Reproduce

1. Add to canvas reaction with atoms or load from file:
   ket-cascade-reaction-2-1-1-atoms.zip
   
2. Click on layout or make save/load to/from RDF actions

Actual behavior

• The length of the tails is bigger than 0.5, the length of the head arrow is bigger than 6.5, size of arrow is bigger than 7:
  

Expected behavior

• Total length of Multi-Tailed Arrow is 7
  • Length of tail is 0.5
  • Length of head arrow is 6.5
• Total length of the single arrow is 7, this Multi-Tailed arrow can be used as a reference for arrow with correct total length:

Environment details:
Reproduced on RC SA env:

• Ketcher [Version 2.26.0-rc.6] Build at 2024-10-25; 09:57:12;
• Indigo Version 1.25.0-rc.4.0-g8862ccb7e-wasm32-wasm-clang-19.0.0
• Desktop, Windows 11 Enterprise
• Chrome, Version 130.0.6723.70 (Official Build) (64-bit)

Additional context

• 4 tests are added to xls and should be automated
• The defect is detected during retesting of Not correct length of Multi-Tailed Arrow and Single arrow after loading from RDF or Layout action #2555, but initially it's related to Update layout for pathway reaction on canvas #2309

Need to check when Remote env will be available to define it is Indigo or Ketcher issue.

Looks like it could be fixed by #2610, but length of spine becomes bigger
