fix(linux): add missing yaze_gfx_render dependency to yaze_gfx_debug

Fixes linker error on Linux where yaze_gfx_debug.a (performance_dashboard.cc)
was calling AtlasRenderer::Get() and AtlasRenderer::GetStats() but wasn't
linking against yaze_gfx_render which contains atlas_renderer.cc.

Root cause: yaze_gfx_debug was only linking to yaze_gfx_types and
yaze_gfx_resource, missing the yaze_gfx_render dependency.

This also fixes the undefined reference errors for HttpServer methods
which were already properly included in the agent.cmake source list.
