The backend returns naive UTC datetime strings (no Z suffix). dayjs was treating
them as local time, so staff in ET saw UTC times. Added treat_as_utc param to
iso_datetime_formatter (default false, zero breakage to existing call sites) that
appends Z before parsing so dayjs converts to browser-local time on display.
Applied to all print timestamp call sites in badge list (first/last print visible
row + debug row) and to created_on/updated_on in the debug row.

Three redundant store fields encoding the same AM/PM choice replaced with a single
`use_12h: boolean` in PresMgmtLocState. iso_datetime_formatter gains a third param
(use_12h: boolean | null = null) that auto-resolves 24h↔12h format name variants via
a symmetric FORMAT_PAIRS lookup — null default leaves all ~100 existing call sites intact.
Toggle surfaces in three places: Clock icon in session time chip (hidden button, same
visual), event Options modal Display section, and session Options modal Display section.
