Changing time zone in mobile app shifts time instead

The bug

Originally reported this in #25882

When a photo is saved from an app (so far I have Facebook Messenger as an affected source) to my phone, it does not upload to Immich correctly, resulting in the timezone being incorrect and not being able to be changed. When the timezone is attempted to be changed, the time shifts instead.

TrueNAS Scale 25.10.1

Version of Immich Server

v2.5.6 (TrueNAS App version 1.11.17)

Version of Immich Mobile App

v2.5.6

Platform with the issue

• Server
• Web
• Mobile

Device make and model

Samsung S25 Android 16

Additional information

I have attached a zip containing a photo that has been processed by Messenger and exhibits the behaviour.
I tested and can confirm that changing the timezone on the same uploaded asset via the web does succeed, and show correctly on mobile. However it then exhibits the same original behaviour, just shifting the time, when I try and change it again from mobile.
I also confirmed that changing other assets that I took locally or were not downloaded from Messenger do allow me to change the timezone on mobile.

This also happens on web, it seems
