Element Android uses outdated timezone for Almaty (UTC+6 instead of UTC+5)

### Steps to reproduce

Summary
Element Android displays message timestamps with the wrong local time in Kazakhstan.
Since March 2025, Kazakhstan officially switched to UTC+5 (permanent, no DST).
However, Element Android still assumes Asia/Almaty is UTC+6, which causes all events to appear 1 hour ahead of the correct local time.

Steps to Reproduce

Set Android system timezone to Asia/Almaty.

Ensure system clock shows the correct local time (UTC+5).

Open Element Android and view any message.

Compare the displayed timestamp with system time.

Expected Result
Message time matches system clock (UTC+5).

Actual Result
Element Android shows timestamps +1 hour ahead, as if Almaty were UTC+6.

### Outcome

What did you expect?

Element Android should display message timestamps according to the correct current timezone of Asia/Almaty (UTC+5), matching the system clock on Android and other Matrix clients.

What happened instead?

Element Android still treats Asia/Almaty as UTC+6, so all message timestamps appear 1 hour ahead of the actual local time, even though the system clock and other clients show the correct time.
