Auto-Delete Rules Account Block for React

Edit HISTORIES: each has an id, a name, a noun for sentences and counts, the number of items by age, where the first entry is the as-of month, the second the month before, and so on. OLDEST holds the items of the oldest months, typed, for the popover. A rule keeps this month and the months before it up to its length, so 3 months keeps the as-of month and the two before it; the day it cuts at is worked out from AS_OF. Keep OLDEST equal to the oldest entries of counts, or the six oldest will not be the oldest.

All of it. Apply saves the rules in this page and says what the next run would delete; no item is removed anywhere, and the status line says so. To make it real, save the rules on your server and let a scheduled job delete what they select; compute the counts there too, and show this page's sentences from what the server reports. Keep the confirmation: a rule that deletes history cannot be undone by the person.

When the rules you are about to apply would delete more than 100 items beyond what the saved rules already delete. It says how many and of what, Cancel has focus, and the action is the destructive Button; Escape closes it and focus returns to Apply. Below that number Apply saves at once. Once rules are saved the same choice asks nothing: nothing new would be deleted.

The six oldest items, across all kinds, that the rules as they stand would delete, with their kind and day. It is a popover, so Escape closes it and focus returns to its button. When no rule would delete anything the button waits quietly and says so if pressed.

The select sits under each kind's name and sentence, each row keeps its height whatever the rule says, and the foot stays pinned to the bottom of the screen with its status over Apply rules and Discard. A row whose rule you changed carries a Not applied badge until you apply or discard it.

Each select has a label that names its kind and is described by the sentence under it, so its effect is read with it. The status line is polite and present from the start, and says how many rules changed. Apply and Discard wait quietly when nothing changed and explain themselves if pressed, rather than disappearing.
