fix: default status filter to 'all' to show archived-only projects

Bug reported in rpamis/comet#72: when all changes are archived (e.g.
plain OpenSpec projects without comet metadata), the default 'active'
filter showed '没有匹配的 change' even though the API returned data.
Default to 'all' so users see every change immediately.
