Sectors Page:

PoRep:

Documentation page not shown as it links to the known docs.

Proposed Changes

Removed Clarity (VMWare CSS Layer) except from the Config Picker page.
Built a unified style like Clarity (font, size, colors)
Hide the page until it's mostly styled (though maybe not loaded).
Bootstrap 5 (the only one that's module-capable), mostly requesting dark components.

Additional Info

The super-small screen makes a hamburger menu that doesn't work. I doubt this is a real problem, but it's ugly.

Tables could use some restyling to match clarity, or at least the background color + there seem to be some regressions on the sector table pages that should get fixed, but other than that I like where this is going.

(I'll try to start some light refactor to Lit + Jsonrpc to start the train of putting all the ui code within one framework.)

Apart from what Magik pointed out:

1. Add a grid to main page
2. Docs should open in a new tab
3. We should filter out completed task list for winpost tasks. They clog the display and prevent users to see useful info.

1. Fix the pipeline page
