Upgrade material3 dependency from alpha to stable

[HayatoYagi]

Problem

libs.versions.toml specifies material3 = "1.10.0-alpha05". Shipping an alpha dependency in a release application risks:

• Breaking API changes between alpha → stable
• Unexpected visual regressions from alpha bug fixes
• User-facing bugs from unfinished alpha features

Suggestion

Pin to the latest stable release of androidx.compose.material3. Check https://developer.android.com/jetpack/androidx/releases/compose-material3 for the current stable version.

Impact

Stability — alpha dependencies can change or break between releases.
