Add some basic dashboard widgets

[dkotter]

What?

Adds the framework for registering new dashboard widgets and adds two to start: AI Status and AI Capabilities

Why?

The admin dashboard in WordPress provides a quick, at-a-glance place to get an overview of your site. Adding in some AI dashboard widgets can provide more value there.

How?

• Adds the framework to easily register dashboard widgets
• Adds an AI Status dashboard widget that will render a simple getting started guide if things aren't set up yet. If things are setup, will show which Providers are connected and which Experiments are turned on
• Adds an AI Capabilities widget that will render how many Abilities we have (same output that's on the Abilities Explorer page) as well as what AI capabilities each registered Provider has

Use of AI Tools

Planned approach and executed that plan using Claude Code running Opus 4.6. Tested and cleaned things up manually.

Testing Instructions

1. Pull this PR down and run npm i && npm run build
2. Add a AI Provider plugin and set that up
3. Go to the Dashboard page and ensure you see an AI Status and AI Capabilities widget
4. Turn Experiments on/off and ensure they are reflected there
5. Do the same for individual Providers

Only adjustment here is to "Enable a feature or experiment" and a column between Connectors and Experiments for Features that will include the Image Generation and Editing one underway.

I think it's likely that migrating Image Gen to be a Feature will happen in the next release so going to punt this to that release as well. I can come back and make this change once that has happened

That works for me, I'll add a reference from this PR to the Experiments > Features open issue.

Sorry, to be more specific, was going to punt this entire PR until the next release, though happy to merge this as-is if we want it in 0.6.0 (noting this is just a minor PR so no real issue holding this for a bit)

No strong opinion either way, plenty other things to try and wrap for 0.6.0 so will leave this here and we can YOLO into it if we want or punt and worry more in 0.7.0.
