Address Dark Mode Divider Visibility Issue by Updating Surface Colors

[FelberMartin]

Description

This follow-up issue to the problem discovered in this PR discussion aims to resolve the divider visibility problem in dark mode due to the M3 design specification flaw. Specifically, the colors surfaceVariant and outlineVariant are both mapped to neutral-variant30, making dividers invisible in dark mode.

In #76 we quickly fixed this issue by assigning a different value to outlineVariant for dark mode

Tasks

• Dependency Update: Upgrade to the latest M3 version that includes surfaceContainer (or another suitable alternative) if available.
• Replace SurfaceVariant: Update all instances of surfaceVariant with surfaceContainer (or another suitable color).
• UPDATE: As discussed in the communication team meeting and with Ramona, disable the dynamic color schemes for the android app as we value the consistency of Artemis apps over the Android user customizability
