Change page date/times to display in local time based on style timezone setting

[chiizujin]

Brief overview of PR changes/additions

The page command currently shows page date/times in UTC. This changes the date/times to the local time zone based on the setting in style.

Motivation for adding to Evennia

Show local time for pages.

Hm, I don't think this is correct. While the default time zone for the server is UTC, it doesn't have to be. This is configured by the settings.TIME_ZONE setting. If this is changed, I'm pretty sure the Msg objects (page.date_created) will be set in that time zone, and then this solution will be wrong.

What should be done here is instead to convert from the server TIME_ZONE (also if it's not UTC) to the player's time zone.

When looking at the value of page.date_created, the messages always seem to have the time in UTC, no matter what the server's time zone setting is at the time of creation. I may be missing some other piece of the puzzle somewhere, but that's why I did a conversion from UTC to the style timezone setting.

However, I think the better solution is to convert the time to the local time zone if the two time zones aren't the same, whch is probably how I should have done it in the first place. This way it doesn't matter what the time zones of the server or page.date_created are; it gets converted if it's not the requested one. I've committed a change to do this. I'll do the same in the mail PR if you're OK with this solution.

Here's an example of the UTC times in the messages (this is with the current behaviour):

>py evennia.settings.TIME_ZONE
Australia/Sydney

>page me TEST 1
Account Chiizujin pages: TEST 1
You paged Chiizujin with: 'TEST 1'.

>page
Your latest pages:
 03:22:50 to Chiizujin:> TEST 1
 03:22:50 from Chiizujin:< TEST 1

page.date_created:

2024-04-28 03:22:50.823627+00:00
2024-04-28 03:22:50.823627+00:00

>py evennia.settings.TIME_ZONE
US/Central

>page me TEST 2
Account Chiizujin pages: TEST 2
You paged Chiizujin with: 'TEST 2'.

>page
Your latest pages:
 03:24:43 to Chiizujin:> TEST 2
 03:24:43 from Chiizujin:< TEST 2

page.date_created:

2024-04-28 03:24:43.674000+00:00
2024-04-28 03:24:43.674000+00:00

For context, the UTC time according to https://www.timeanddate.com/worldclock/timezone/utc was:
03:26:03 UTC

I'm not sure if this is related, but django.utils.timezone.now() always returns a UTC time, regardless of the server's time zone setting.

So, I discovered something interesting while poking at this, and I believe the current timezone settings are actually bugged. 😆 I'm going to file an issue since it got a bit complicated but I'll reference it here.

OK, I'll park this and #3504 until you've go that sorted.
