[BillLeoutsakosvl346]

Summary

• Use ChipInput for the API-key and branding color fields, retaining the reveal control, color swatch, validation, and existing layout.
• Add a leading-content slot to ChipInput and remove the unused local field-style helpers.

Type of Change

• Refactor

Testing

• Workspace type checks, lint, import/API audits, and documentation checks pass.
• 346 EMCN tests and 4 relevant consumer tests pass.
• Browser comparison of original and updated field markup in light/dark themes covers valid/invalid colors and hidden/revealed dummy API keys. Fixtures use application CSS; no live credentials were saved.

Summary

This PR consolidates the remaining API-key and branding-color fields onto the shared ChipInput component.

• Adds a custom leading-content slot while preserving the existing icon fallback and trailing-adornment API.
• Migrates the BYOK secret field without changing masking, reveal, autocomplete, or edit behavior.
• Migrates branding color fields while retaining swatches, normalization, validation, and monospaced input text.
• Removes the obsolete local chip-field styling helpers and their barrel exports.
• Adds focused coverage for input identity and focus retention when leading content changes.
