The two indexes ix_sps_server_open and ix_sps_server_recent were
byte-identical because SQLAlchemy's Index(name, *cols) form drops the
DESC ordering the spec intended. Rather than reach for text("left_at
DESC"), drop the second index entirely — SQLite scans the ASC index
backwards at no measurable cost. Spec and plan updated to match.
