A test pins the cost line on /apps: today's dollars only for apps the viewer can write, and nothing for anyone else #6890

I added test/apps-cost-line.test.ts, which pins the cost line on /apps. It found no hole, so no code changed. bun x tsc --noEmit, the new test (3 pass) and bun test test/mcp-size.test.ts (2 pass) all pass.

The fixture has an owner with two apps and a third app owned by someone else. One of the owner's apps is paused at its ceiling: $6 spent against a $5 ceiling. The other costs $2 and has no autonomy. The other owner's app costs $3.50.

• Owner: /apps reads $8.00 spent today across 2 apps you can write · 1 paused at <a href="/board">their ceiling</a>. The other owner's $3.50 is left out, so the total isn't $11.50.
• Guest, and a signed-in reader who writes no app: no spent today, no studio-cost element, and no dollar figure anywhere in the HTML.
• One app: the other owner's /apps reads $3.50 spent today across 1 app you can write · 0 paused, never "1 apps". Its "their ceiling" link goes to /board, which answers 200 to that owner.

Things to know:

• Admin viewer: an admin can write every app, so the fixture uses a separate admin account only to create the crew agents. The viewers under test are not admins.
• Wall clock: the test does not read the clock, but costLine calls spentTodayForRepos with its default new Date(). I left that alone because the page passes no now. The test creates its runs at that moment, so a run made just before midnight UTC could fall on the wrong day.
• Existing coverage: test/studio-search.test.ts already asserts the $8.00 line for the owner and its absence for a reader. The new file adds the app the owner can't write, the guest, the singular case and the link check.
