Task: Document the moved process classes in ores.analytics.quant component docs

Component documentation reflects the new domain/service additions so future readers understand the process abstraction without reading ores.synthetic history.

• component_overview.org and the .puml diagram both updated and regenerated; diagram builds cleanly.

Extended component_overview.org's Summary with a paragraph on the stochastic-process area (origin in ores.synthetic, why it moved), and added the new types to Inputs/Outputs/Entry points/Dependencies. Added sibling domain and service PlantUML namespace blocks (the existing diagram groups the CRM types under a crm namespace that doesn't actually match the C++ namespaces — left that pre-existing drift alone and used the real domain=/=service namespaces for the new content). Regenerated the PNG via the CMake diagram target.

Manual QA scenarios (scaffolded via compass add test_scenario, run through the QA Validation Runner panel) that verify this task. Link new ones here as they're created; the scenario doc itself links back via its "Verifies task" field.

component_overview.org and the PlantUML diagram both updated; generate_ores.analytics.quant_diagram built cleanly and the PNG was regenerated. This was the story's last open task.
