docs(theme): align palette references with the updated Green and Brown steps

Replace the old Green Default #123328 and Dark steps in the component docs,
brand color steps, runtime theme contract, token guide, loading screen doc and
the @hm-design/ui AI design rules. check:ai-docs passes. Remaining references
elsewhere are left for the final documentation consistency pass.
