Budget records now show the cancelled status only when a budget is actually cancelled. This keeps the status bar clearer and reduces confusion for users reviewing budget progress.

before this commit, cancelled state was showing in the second position in the statusbar after the draft and it was always visible in the statusbar.

after this commit, the cancelled state will be moved to last position and only will show when the record is in the cancelled state.
