Show times in a configurable time zone

SRG sends times with an offset (e.g. 13:55+02:00). They are stored as
DateTime, which deserialisation converts to server-local time, and two
places then wrote that straight into text: the "[dd.MM HH:mm]" prefix
on upcoming livestream names and the timestamp in recording file names
(DateTime.Now). On a server running in UTC both were two hours behind
Swiss time, e.g. a qualifying starting at 13:55 was listed as 11:55.

A new "Display Time Zone" setting (IANA id, e.g. Europe/Zurich) now
decides the zone for both; empty keeps the server's zone, and an
unknown id falls back to it rather than breaking the listing.
Utilities/DisplayTime does the conversion.

Also fixes PremiereDate on upcoming livestreams, which was set to that
server-local value although Jellyfin expects UTC. It was only correct
on UTC servers; it is now converted, like the other channel items.

Verified on simulated UTC and Europe/Paris servers: the same instant
gives 11:55 / 13:55 / 07:55 for server zone / Europe/Zurich /
America/New_York, and PremiereDate is 11:55 UTC on both.
