draft: feat: Describe modal for Project Status

[royendo]

Adds a resource describe modal to the Project Status resources table. Clicking the "View spec" action on any resource opens a dialog with structured, human-readable details about that resource.

Supported resource types:

• Connector — driver, environment variables, properties, provision args
• Source / Model — general info (input/output, change mode, refresh, materialize, incremental, partitioned), SQL in code format, properties, stage, runtime stats, retry config, tests
• Metrics View — data source, time config, dimensions, measures, caching, AI instructions, security policy, annotations
• Explore — general settings, dimensions/measures selection, security policy
• Canvas — general settings, layout, clickable components (drills into component detail with back navigation), variables, pinned filters, security policy
• Component — renderer, renderer properties, input/output variables
• Theme — color swatches (primary/secondary), light/dark mode overrides
• Alert / Report — navigates to existing /-/alerts/{name} and /-/reports/{name} detail pages

All resource types show display name (when available) and description in the dialog header. Unsupported types fall back to a JSON view.
