Contract: one organization and person page #633

Pillar: P1 Feed (umbrella #587). Contract: one of the duplicated screens the studio/dev split left behind. One run, fresh from today's main.

The job: see an organization or person and what they make.

Survivor: one owner page serving both faces' jobs: their apps first, then repositories, then teams for admins.

Removed in this same pull: the studio branch in src/web/pages/org.ts and whichever half repeats the other.

The path: a person from a post's name or the explorer wants to know who this is; primary action open their top app; next that app.

Acceptance.

• [ ] One renderer for this job, for every repository and every viewer; the other code and its tests are deleted, not hidden.
• [ ] Every old URL still answers (the survivor, or a redirect); ?mode=dev on it shows the survivor.
• [ ] Nothing the removed screen did is lost: the pull lists each thing it showed or did and where it lives now (or why nobody needs it).
• [ ] Minimal, not bare: one primary next action, white space at every width, nothing the person does not need now.
• [ ] Looks of the path at phone and desktop widths on the pull; the full check green.

Start from: src/web/pages/org.ts.

Must not touch: the release workflow, the chart, other repositories.
