Give LITE the bundled recipes, three of its own, and its own mark

LITE used to hand back the RECIPESCAM mark instead of the user's own
watermark and treated every saved recipe as PRO. That is the wrong half of
the product: the looks the user dials in are the reason to shoot, the
printing and the paid extras are the reason to pay.

What LITE now owns outright: the eight film sims, the bundled recipes, up
to three recipes of its own, its own watermark text (in one basic face,
the platform families stay PRO), the plain frames, and FAVORITED. What
needs PRO: the three printed frames, the GPS stamp, the other fonts, and
the next recipe past the limit.

- entitlement: `Look` is {frame, gpsWm}; `isFreeRecipe` is gone, the
  recipe gate is a count now, decided in App (`liteSaveBlocked`).
- export: a LITE export draws the custom mark AND the RECIPESCAM mark, so
  `liteMark` joins `watermark` in the options and the stamp block loops
  over both with one set of bounds.
- panel: past the limit the strip's trailing chip is a `+` carrying the
  PRO tag, which names the build instead of opening the form.
