Show every time in US Eastern (America/New_York)

Webapp: config.DISPLAY_TZ (default America/New_York) and a local_dt
filter that renders datetimes, ISO strings and Unix timestamps as e.g.
"2026-10-05 13:54 EDT", DST included. Used for the ServiceNow tick list,
technician to-do, imaging tiles and detail page; timestamp_fmt (reports,
backups, enrollment) goes through it too instead of relying on the
process TZ. CSV report_date is Eastern with its offset. Evidence-pack
months are Eastern calendar months, so a wipe late on the 31st lands in
that month rather than the next.

Blancco: init points the new root's /etc/localtime at America/New_York
so the GUI clock is local. Report timestamps keep their explicit
offset; report.utc_offset stays 0 since a fixed offset cannot follow DST.
Report file names stay UTC, as Blancco's own Save names them.
