Enhancement: Refresh remaining foundational deps to official sample baselines

[Gurupreet]

Problem: Beyond the already-filed Kotlin/Nav/Lifecycle/Coil issues, several base deps still trail official samples a lot.

Proposed solution: Track upgrades for:

• activity-compose 1.8.2 -> 1.13.0
• core-ktx 1.12.0 -> 1.18.0
• appcompat 1.6.1 -> 1.7.1
• material 1.11.0 -> 1.14.0-rc01 or latest stable
• optionally align room, hilt, okhttp, coroutines where not already covered

Why now: Official compose-samples catalogs are much newer; current repo versions are in buildSrc/.../Versions.kt.

References: See dependency versions in compose-samples buildSrc Versions.kt and ComposeCookBook buildSrc/Versions.kt.
