feat(monitoring): add host RAG trace observability

* test: cover frontend CRUD smoke flows

* test: add bot CRUD smoke coverage

* test: add bot/pipeline advanced flows and cross-resource tests

- Bot enable/disable toggle with state persistence
- Bot detail tab switching (Configuration, Logs, Sessions)
- Bot form dirty state and save button behavior
- Bot name validation error display
- Pipeline tab switching (Configuration, Dashboard)
- Pipeline form dirty state
- Pipeline name validation error display
- Cross-resource flow: create pipeline then bind to bot
- Empty states for bots, pipelines, knowledge bases, MCP servers
