CIP stereo labels intersect with bonds or are placed too close to the structure in macromolecule layout modes

**Description:**
In Flex, Snake, and Sequence macromolecule modes, CIP stereo labels (R/S) are rendered in a way that they either intersect with nearby bonds or are placed too close to atoms/bonds. This makes the labels visually cluttered and difficult to read, reducing overall clarity of the structure.

**Steps to Reproduce**
1. Open file and copy it to Ketcher . File: [ring-and-chains-with-stereo.ket](https://gist.githubusercontent.com/zefiris87/a06e51d7ba1f677d623416f407d8b82e/raw/5724180fcac62791c15a758ac663b799e373504f/ring-and-chains-with-stereo.ket)
2. Press Calculate CIP button

3. Switch to any macromolecule mode (Flex, Snake, Sequence).

4. Observe how (R)/(S) labels intersect bonds or sit too close to them.
**Actual behavior**
CIP labels sometimes overlap with structure elements or are positioned directly adjacent to bonds without spacing, especially in compact ring systems.

**Expected behavior**
CIP stereo labels should be rendered with enough padding from the atoms and bonds to ensure readability and avoid visual overlap. Label positioning should dynamically adapt to avoid intersections.

This bug was found while testing: https://github.com/epam/ketcher/issues/6995

Load ring-and-chains-with-stereo.ket in Ketcher, calculate CIP, and reproduce the issue in Flex, Snake, and Sequence modes. Start from the macromolecule layout and CIP-label rendering entry points; done means R/S labels have visible spacing from atoms and bonds without intersections in the reported compact structures.
