#5578 - Peptide section for ambiguous monomers should have "Ambiguous Amino Acids" name

[Copilot]

Problem

The Peptides section in the monomer library displayed "Ambiguous Amino acids" with an incorrect lowercase 'a' in 'acids', which did not match the capitalization requirements specified in #5186.

Before:

Expected:

Root Cause

The MonomerGroups.PEPTIDES enum was defined as 'Amino acids' (lowercase 'a') in both the ketcher-core and ketcher-macromolecules packages. When the library creates the section title for ambiguous monomers, it uses the template:

groupTitle: `Ambiguous ${libraryGroupName}`

This resulted in "Ambiguous Amino acids" instead of the correct "Ambiguous Amino Acids".

Solution

Updated the MonomerGroups.PEPTIDES enum value from 'Amino acids' to 'Amino Acids' in:

• packages/ketcher-core/src/application/editor/shared/constants.ts
• packages/ketcher-macromolecules/src/constants.ts

Also updated a test description for consistency.

Testing

✅ All 481 unit tests pass across all packages
✅ Build successful for all packages
✅ Linting, formatting, and type checking pass
✅ No breaking changes introduced
