feat: ingredient/tag search on My Recipes, QR code on printed recipes

My Recipes search previously only matched title/description; now also
matches ingredient rawName and tags, mirroring the public search
improvement from earlier. Hit and fixed a real bug along the way:
embedding drizzle column proxies from a foreign table inside a raw
sql`` fragment passed to db.query.recipes.findMany's `where` gets
rewritten to the wrong table alias by the relational query builder,
producing broken SQL — worked fine in the plain query builder used by
/api/v1/search, but not here. Fixed by using literal SQL identifiers
for the ingredients subquery instead of column proxies.

Recipe print pages get the same QR-code treatment shopping lists got
earlier, gated on visibility !== "private" (both public and unlisted
resolve at /r/[id]).
