fix(frontend): restore profile analytics for all object types

[Seme30]

Part of #789.

Problem

Next.js profile analytics fail or mis-render depending on type. Term and collection profiles error. Report and user profiles load but show the wrong names and unformatted percents.

Related API work is in #788; this issue is the Next.js profile UI.

Current gaps

• /profile?id=1&type=term and /profile?id=1&type=collection → Next.js "Unable to load profile". Razor shows an empty analytics shell.
• /profile?id=16&type=report on Next.js shows 3 runs, 2 users, 42s, a chart, Top users, and Failures — but row titles are the section name (Top Users) and percents print as 0.3333333333333333%.
• /users?id=2 analytics on Next.js has the same label/percent bug (Top Reports, raw floats).
• Razor profile pages stayed on - Runs / - Users in this docker run even after waiting for network idle (likely Razor AJAX). Treat Razor empty charts as a separate host note, not a Next.js pass.

Frontend references

• frontend/app/profile/page.tsx
• frontend/components/profile/
• GET /api/profile/chart|users|reports|fails|run-list|stars|subscriptions

Definition of done

• Term and collection profiles render an analytics (or explicit unsupported) state instead of a generic error.
• Top users / top reports rows show the seeded person or report name.
• Percents are formatted (for example 33%), not raw floats.
• Frontend tests cover term/collection load failure and the label/percent rendering.
