feat(web): rebuild home as "The Floor" on the Pressing Plant system

Home reads /api/requests + /api/wanted + /api/artists: summary tiles
(on the press / pressed / wanted / watching), the on-the-press job list
(state -> stripe + chip + stepped bar via describeJob; needs-attention shows
a literal recovery note), a request form (test hooks preserved), an empty
state, and a recently-pressed deadwax list. Verified in the real app (dark
desktop + mobile); light theme matches the approved comp.
