barbie-bot 862430e586 Add index on readouts(user_id, taken_at) ...

MeasurementsController#index orders by taken_at desc; without an index
this scan grows linearly with the readout count. The composite index
on (user_id, taken_at) covers both the implicit user_id filter from
the association scope and the ORDER BY clause.
