Fix minimal distances for mult-tail validation in KET format

[AlexanderSavelyev]

Steps to Reproduce

1. Insert structure from smiles "CC"
2. Insert default multi-tail arrow
3. Increase the bond length twice
4. Select all
5. Save as Ket, copy the ket file into clipboard buffer
6. Paste the ket file

Actual behavior Error message appears - cannot deserialize input JSON

Expected behavior No errors, Structure is pasted but with a smaller size The following validation rules should be changed for KET file (only for KET, the UI behavior should not be changed)

MIN_TAIL_DISTANCE - 0.01. MIN_HEAD_LENGTH - 0.01. MIN_TAIL_LENGTH - 0.01 MIN_TOP_BOTTOM_OFFSET - 0.01 MIN_HEIGHT - 0.01

Desktop (please complete the following information):

• Version 2.26rc2

Note

• Issue is related to this task - https://github.com/epam/ketcher/issues/5104, tests should be updated

12 manual tests and files are updated, minimal sizes are retested on UI and for loading from KET on Nightly env.

• Minimal sizes on UI are still working as it was:
  • Minimal length of spine without tails = 0.5:
  • Minimal distance between tails = 0.35
  • Minimal length of tail = 0.4
  • Minimal length of head = 0.5
  • Minimal X distance between head and top/bottom tails = 0.15:
• As for minimal sizes for loading from KET, they equal 0.01, but there is no chance to verify validation for MIN_HEIGHT - 0.01 as we have the same MIN_TOP_BOTTOM_OFFSET - 0.01, this is part of MIN_HEIGHT.
  • After loading of Multi-Tailed arrow with minimal sizes, it looks like that, but it can be adjusted to normal size using resizing of head, tails and spine:
• One defect is detected related to changes of minimal sizes - https://github.com/epam/ketcher/issues/5786
