An app's studio page names its Server-Timing phases: session, each read, render #3642

An app's studio page (studioApp) now reports its Server-Timing phases instead of one opaque number. The new test and the 199 tests under test/studio pass. I couldn't run tsc --noEmit here: bun couldn't write to its temp directory, so bun install and the type check both failed. The forge's check will be the first type check of this change.

What changed

• src/web/studio/app.ts calls notePhase and timePhase from src/core/route_timing.ts, the way releases.ts and explore.ts do.
• The phases are session (from takeSessionTime), then one per read, then render.

- Reads: opened, crew, pulls, shipped, spend, decisions, latency, history, autonomy, panels, now, following and policy. - spend, decisions, latency and autonomy only appear for a viewer who can see the owner's facts, because the page skips those reads for everyone else.

• The page renders exactly as before. The only reordering is that policyLine is now awaited just before the body is built, so it can be timed on its own.
• test/studio-app-timing.test.ts signs in, GETs /alice/vault/app, and checks that every phase above is in Server-Timing as name;dur=N.N. It fails without the change.

Left out

• No caching.
• I added no phase for autonomy to the test, since the repo in the test has autonomy off.

To try it, GET any app's studio page and read the Server-Timing header.
