fix: stock correction not working for bottle type and manual calculation mode (#133)

- Fix bottle type: submitStockCorrection used blister formula for baseTotal
  but getMedTotal uses only looseTablets for bottles. Now uses getPackageSize()
  which handles both types correctly.
- Fix manual mode: same-day taken doses were counted as consumed after a stock
  correction (>= comparison with date-only timestamps). Changed to > so doses
  on the correction day are excluded.
- Add agent instruction: only release-manager may create PRs/push/merge.
