Job Tracker

Dates now show on every phone, going back and forth on a status no longer piles up stages, cards are sorted by date and left-aligned, and a status summary sits under the count.

Stage history for each application, numbered cards with the date applied, and the status picker now shows the chosen status.

Fixes for the first version: tidier layout, a hint when company or role is missing, quicker tests.

First version: add, list and edit job applications, each with one status.
