Snooze (#933): brief user section on Tickets, full developer guide
Snoozing is small to use and large underneath, so the analyst-facing
description is a section on the existing Tickets page rather than a page
of its own, and the detail goes in a dedicated developer guide.
Tickets.md — new "Snoozing tickets" section, plus the three places that
were now incomplete: the right-click menu list, Reopen on Customer Reply
(the same four doors also wake a snoozed ticket), and Settings → General
(start of the working day).
Snoozing-Tickets-Developer-Guide.md — the schema and why there is no
table, why waking is the clock rather than a cron and what that forbids
(never test IS NOT NULL for "asleep"), the two predicates and why the
"only sleeping" one degrades to 1=0 rather than an empty string, the
schema gate that keeps the inbox alive before Database Verification has
run, server-side preset resolution and the rule that a preset is dropped
when its name would stop being true, the four inbound doors, what snooze
deliberately doesn't touch (SLA, search, updated_datetime, status), why
it is on the ticket rather than the analyst, how it was verified, and
how to extend it.
