## Summary Sets the shared `RecordCardHeaderContainer` height to `32px`, so board and calendar card headers use the same common header size. Updates the board fetch-more card-height estimate to use the same `32px` header value. Reduces the calendar card header/content gap by removing the body top padding while keeping the existing side and bottom padding. ## Screenshots Before:  After:  ## Validation - Browser verification on `http://apple.localhost:3001/objects/opportunities?viewId=0433d066-dda7-4b2c-89e5-04d4792d193c`: visible calendar card body padding computes to `0px 4px 4px` - Browser verification on board view: visible board card headers compute to `32px` - Browser console errors: none - `git diff --check` - `prettier --write` on changed files - `oxlint --type-aware` on changed files in the running checkout
