fix: bd ready now shows in_progress issues (#894)

The RPC server's handleReady() was explicitly setting Status to
StatusOpen, which overrode the intended behavior where an empty Status
field matches both 'open' and 'in_progress' issues.

Removed the Status field assignment so it remains empty (zero value),
allowing the SQLite storage layer to correctly return both statuses
as documented in the help text.

Fixes #5aml
