fix(web): correct knowledge dialog draft state

[lyzno1]

Summary

• scope knowledge dialog state to a single open session and keep React state updaters pure
• isolate inline name editing with commit, cancel, IME, and focus restoration behavior
• avoid persisting derived rerank settings during unrelated draft edits and align the title button/input box model
• replace CSS implementation assertions with user-visible draft, keyboard, focus, and config preservation coverage

Testing

• pnpm -C web test features/agent-v2/agent-detail/configure/components/orchestrate/knowledge/__tests__/index.spec.tsx
• pnpm -C web exec eslint features/agent-v2/agent-detail/configure/components/orchestrate/knowledge/dialog.tsx features/agent-v2/agent-detail/configure/components/orchestrate/knowledge/__tests__/index.spec.tsx
• pnpm -C web type-check
• git diff --check
