* feat: add session message monitoring tab to bot detail dialog Add a new "Sessions" tab in the bot detail dialog that displays sent & received messages grouped by sessions. Users can select any session to view its messages in a chat-bubble style layout. Backend changes: - Add sessionId filter to monitoring messages endpoint - Add role column to MonitoringMessage (user/assistant) - Record bot responses in monitoring via record_query_response() - Add DB migration (dbm019) for the new role column Frontend changes: - New BotSessionMonitor component with session list + message viewer - Add Sessions sidebar tab to BotDetailDialog - Add getBotSessions/getSessionMessages API methods to BackendClient - Add i18n translations (en-US, zh-Hans, zh-Hant, ja-JP) Generated with [Claude Code](https://claude.ai/code) via [Happy](https://happy.engineering) Co-Authored-By: Claude <noreply@anthropic.com> Co-Authored-By: Happy <yesreply@happy.engineering> * refactor: remove outdated version comment from PipelineManager class * fix: bump required_database_version to 19 to trigger monitoring_messages.role migration * fix: prevent session message auto-scroll from pushing dialog content out of view Replace scrollIntoView (which scrolls all ancestor containers) with direct scrollTop manipulation on the ScrollArea viewport. This keeps the scroll contained within the messages panel only. * ui: redesign BotSessionMonitor with polished chat UI - Wider session list (w-72) with avatar circles and cleaner layout - Richer chat header with avatar, platform info, and active indicator - User messages now use blue-500 (solid) instead of blue-100 for clear visual distinction - Metadata (time, runner) shown on hover below bubbles, not inside - Proper empty state illustrations for both panels - Better spacing, rounded corners, and shadow treatment - Consistent dark mode styling * fix: infinite re-render loop in DynamicFormComponent The useEffect depended on onSubmit which was a new closure every parent render. Calling onSubmit inside the effect triggered parent state update → re-render → new onSubmit ref → effect re-runs → loop. Fix: use useRef to hold a stable reference to onSubmit, removing it from the useEffect dependency array. Also add DialogDescription to BotDetailDialog to suppress Radix aria-describedby warning. * fix: remove .html suffix from docs.langbot.app links (Mintlify migration) * style: fix prettier and ruff formatting --------- Co-authored-by: Claude <noreply@anthropic.com> Co-authored-by: Happy <yesreply@happy.engineering>
