fix(uploads): migrate ImageVideoDescription icons to MaterialSymbols

The AI-suggested alt-text chip was using androidx.compose.material.icons.*,
which the project no longer pulls in (migrated to MaterialSymbols a while
back). The file failed to compile until the dep was either re-added or
the icons migrated. Switching to MaterialSymbols.AutoAwesome / .Close.
