fix(credentials): render the credential selector with the editor combobox

[waleedlatif1]

Summary

• Credential selector renders Combobox again instead of ChipCombobox, so credential fields match the combobox and selector pickers around them in the block editor
• ChipCombobox only changes the trigger chrome (30px rounded chip, chip surface), so behavior (search, groups, connect actions, overlay icon) is unchanged

Type of Change

• Bug fix

Testing

• Sub-block editor tests passing (160)
• bun run lint, check:audits, block registry check, and docs-manifest:check passing

The behavioral change appears low risk, but the explicit chip-family component requirement must be satisfied before merging.

1.  Legacy Combobox Violates Standard ▶

Summary

This PR changes the workflow editor’s credential selector from ChipCombobox to the underlying Combobox.

• Credential selection, search, grouping, loading, overlay, and callback behavior remain unchanged because both controls use the same prop contract and implementation.
• The change removes the chip-specific trigger chrome but conflicts with the repository’s explicit requirement to prefer chip-family controls.
