feat(console): improve observer monitor formatting and readability

[Zouuabi]

Summary

• Parse ASCII table output from observer endpoints into proper HTML tables with headers and styled rows
• Add health status indicators (green/red dots) for each component
• Organize observer components as individual cards: Processing Queue, Vector Database, Language Model, Retrieval Stats, Active Locks
• Render system status as a clean key-value grid instead of raw JSON dump
• Add auto-refresh toggle button (10s interval) for live monitoring

Before / After

Before: Raw ASCII tables and JSON dumps in a <pre> block
After: Formatted HTML tables with health indicators, organized in cards

Type of Change

• New feature (feat)

Testing

• Manual testing completed
  • Verified all 5 observer components render correctly (queue, vikingdb, vlm, retrieval, lock)
  • Tested auto-refresh toggle on/off
  • Tested System Status button renders key-value grid
  • Tested with both healthy and empty states
  • Verified dark and light theme compatibility

Files Changed

• openviking/console/static/index.html -- added dashboard container and auto-refresh button
• openviking/console/static/app.js -- ASCII table parser, component card renderer, auto-refresh logic
• openviking/console/static/styles.css -- monitor dashboard card and table styling

Checklist

• Code follows project style guidelines
• No Python changes (frontend-only: JS/CSS/HTML)
• Documentation not affected

PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

⏱️ Estimated effort to review: 2 🔵🔵⚪⚪⚪

🏅 Score: 75

🧪 No relevant tests

🔒 Security concerns Cross-Site Scripting (XSS) vulnerability: The code inserts unsanitized content from the observer and system status endpoints into the DOM using innerHTML without escaping HTML entities. This could allow malicious scripts to execute if the server returns content containing HTML tags (e.g., in component status messages, table cells, or system status values). Affected areas include renderMonitorTable (headers/cells), renderComponentCard (plain text), renderSystemStatus (keys/values), and renderObserverDashboard (component names).

Thanks for the monitor UI improvement. I found three blocking issues that need to be addressed before this can merge.

• parseAsciiTable() does not handle the models observer output format, so the Language Model card will not render as a proper table.
• The frontend assumes a vlm component key, but the backend returns models, which breaks naming and ordering.
• Auto-refresh keeps running after leaving the monitor view and continues overwriting the shared Result pane.

Please address these and I can re-review.

[Bug] (blocking) parseAsciiTable() assumes every comp.status block is a plain tabulate table, but ModelsObserver.get_status_table() prefixes each table with section headers like VLM Models: before the ASCII table. In that case dataLines[0] becomes the section header, splitRow() returns [], and the real header row is rendered as body data. The Language Model card therefore does not render as the formatted table described in this PR. Please strip leading non-table lines or parse section headers separately before calling renderMonitorTable().

[qin-ctx]

[Bug] (blocking) This code assumes the backend component key is vlm, but ObserverService.system() actually returns models (queue, vikingdb, models, lock, retrieval). As a result, this card keeps the raw models label and also falls out of the intended order because both friendlyNames and the order array are keyed on vlm. Please align the frontend mapping with the actual response contract.

[qin-ctx]

[Bug] (blocking) Once auto-refresh is enabled, nothing turns it off when the user leaves the Monitor panel or switches to the System Status view. setInterval(loadObserver, 10000) keeps firing in the background and loadObserver() keeps calling setOutput(payload), so the shared Result pane in other panels gets overwritten every 10 seconds. This is a behavior regression introduced by the new feature. Please clear the interval when leaving the Monitor panel and when switching away from observer data.
