Entry screen is the app: phone frame with a live deck inside

The homepage was a marketing brochure -- a hero paragraph, a "three
steps" explainer and a tag list. It described the gesture in prose
while the actual Tinder deck sat behind /deck/[jobId], reachable only
after signing in AND posting a job. Nobody opening the app ever saw
the product.

Now / renders a phone illustration with the real app running inside
it: the same <Deck>, the same drag physics, real verified pros. On a
phone the bezel collapses and the deck simply fills the viewport --
drawing a picture of a phone on a phone is absurd, and it would eat
the width the cards need.

- Removed the fixed app bar and bottom tab bar. AppShell now renders
  the screen title as an in-flow h1; the bar owned the only h1 on
  every screen, so dropping it silently would have left every page
  headingless. The /jobs "post" action moved from bar chrome into the
  content, since the tab bar was its only other route there.

- getShowcaseDeck(): a deck with no job behind it. getDeck is
  job-scoped (joins jobs for category and location, anti-joins
  swipes), which an anonymous visitor has none of, so this centres on
  the launch city. Eligibility rules are copied verbatim -- nobody may
  appear in the shop window who could not appear on a real deck.

- deck.showcase: the only public procedure in the router. list and
  swipe stay behind clientProcedure. It reads nothing about the caller
  and writes nothing, so a right swipe on the entry screen is purely
  local. No real tradesperson is contacted until a job is posted.

- <Deck> filled a hardcoded 560px desktop box; it now fills its
  container. The card counter moved out from between the two action
  buttons so the thumb zone holds nothing but the two controls.

Verified against the seeded database: 22 eligible pros returned, and
all three seeded traps excluded for the right reason -- Pau Ribas
(22km out, 5km radius), Unverified Ulla (pending), Away Arnau (not
accepting). 7 new integration tests cover exactly that.

Also corrects a label I had written as "Plumbers near you" -- the
showcase deck is not category-filtered and shows every trade.

Includes concurrent edits to the mobile shell, ui/ primitives and
DESIGN.md made outside this session.

typecheck, lint, build clean; 141 tests pass.
