ux(coding-agent): removed static pending icons from edit headers

- Remove the static "pending" hourglass icon from edit and write tool headers to reduce visual noise.
- Update multi-file status lines to use the active spinner icon directly instead of replacing a static icon, ensuring consistent liveness cues.
