* Fix counts graph on narrow devices
Graph and table now align in a column when the device's screen is narrow. Columns widths are bounded to not get too wide
* Rename toLocaleXXX functions
* toLocaleNumber -> localizedNumber
* toLocaleString -> localizedDate
Also cleans up sketchy "card counts" table formatting
* Localize more numbers
Uses locale-based rounding for more numbers now
* Localize graph axis ticks
* Fix future-due graph tooltip
* avoid div by zero (dae)
Ignoring NaN in localizedNumber() could potentially mask a mistake
in the future - better to explicitly handle the invalid case at the
source instead.
