Not correct length of Multi-Tailed Arrow and Single arrow after loading from RDF or Layout action

[ivanmaslow]

Steps to Reproduce

1. Load 2:1:1 reaction from RDF file:
   rdf-rxn-v2000-cascade-reaction-2-1-1.zip
   
2. Click on Save as... and select KET format
3. Observe the preview

Actual behavior

• Total length of Multi-Tailed Arrow is 6.5
  • Length of tail is 0.3125
  • Length of head arrow is 6.1875
• Total length of the single arrow is 6.5

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

4. If you try to save such reaction to KET and load - the "Cannot deserialize input Json"error is displayed because tail is less than minimal size = 0.4, it will be fixed in scope of Fix minimal distances for mult-tail validation in KET format ketcher#5761
   

Environment details:

• RC SA env
• [Version 2.26.0-rc.2] Build at 2024-10-14; 19:59:03
• Indigo Version 1.25.0-rc.2.0-g867ae250b-wasm32-wasm-clang-19.0.0
• Desktop, Windows 11 Enterprise
• Chrome Version 129.0.6668.101 (Official Build) (64-bit)

Additional context

• Also, if user changes sizes of MTA and after that performs Layout, sizes will be changed not correctly as in actual result:
• Issue is detected during retesting of Not correct length of head arrow after loading from RDF or layout action #2453, initially it's related to Update layout for pathway reaction on canvas #2309

Pre-tested on aws_ci environment with Ketcher master and Indigo 2407-branch-ordering branches:

• Ketcher [Version 2.26.0-rc.1] Build at 2024-10-24; 12:25:38;
• Indigo Version 1.25.0-rc.3.18-gcdee98d4-wasm32-wasm-clang-12.0.0
• Desktop, Windows 11 Enterprise
• Chrome Version 130.0.6723.70 (Official Build) (64-bit)

The size of the Multi-Tailed Arrow and single arrow is as expected for cases with molecules, but for atoms length isn't correct:

There is saved ket file after loading of rdf to check sizes:
ketcher (5).zip

The fix is verified 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)

As mentioned in the comment above it works correctly for reactions with Molecules, but for reactions with atoms length isn't correct - the defect is reported - #2583
