chore(deps): Migrate QA ai-agent to testcontainers 2.0.5

Testcontainers 2.0 renamed all modules with a 'testcontainers-' prefix,
so the 1.x coordinates org.testcontainers:ollama and :junit-jupiter no
longer resolve under the 2.0.5 BOM. Rename them to testcontainers-ollama
and testcontainers-junit-jupiter and bump the BOM to 2.0.5. Test sources
compile unchanged (OllamaContainer / @container / BindMode packages are
stable in 2.0). Completes Dependabot #855.
