feat(dashboard): add $table renderer for dashboard outputs

[vkarpov15]

Motivation

• Dashboard evaluation results that include tabular data should render as readable tables instead of raw JSON.
• The $table shape (columns + rows) needs a dedicated renderer to present data with the same visual language used elsewhere in the app.
• This change aims to mirror the table styling used in models.html (header background, padded cells, hover state, borders, and horizontal overflow support).

Description

• Added a new dashboard-table component at frontend/src/dashboard-result/dashboard-table/dashboard-table.js with template dashboard-table.html to render value.$table.columns and value.$table.rows.
• Implemented safe cell rendering via displayValue that stringifies objects and handles null/undefined values gracefully.
• Wired $table support into frontend/src/dashboard-result/dashboard-result.js so getComponentForValue returns dashboard-table when value.$table is present.

Testing

• Ran npm run -s lint and the lint step completed successfully.
• Attempted an automated Playwright UI capture to validate the table rendering, but the local front-end server was not running and the request failed with ERR_EMPTY_RESPONSE (no server at http://127.0.0.1:4173).
