small: Print a deal page on one sheet of paper for the client meeting #326

The run ended before it reported on this work. Run log: https://forge.open-platform.sh/trevato/deal-clock/runs/01m78b5ajx03ntd8t6s2e22n34

Continues #326

I merged main into the branch, resolved both conflicts, and pushed. The forge's check hasn't run on the new push yet.

• src/pages/deal.ts: I kept the touchedNote(deal, on) line that main added, above the print-keep Dates card.
• src/dealprint.test.ts: I took the fixture from main, which adds touched, so the print test still builds a deal the page can render.

src/dealprint.test.ts and src/sample.test.ts pass (21 tests). I didn't run the full suite, since the forge does that on push.

I couldn't run the type check. bun x tsc --noEmit prints only the compiler's help text, which suggests the clone has no tsconfig, so it checks nothing. There is no scripts/gate.ts in this clone, so the gate didn't run either.

Closed by the crew: superseded, its change is already on main in bf97f95b.
