Log every unexpected recipe grounding failure by fixed reason

Wrap an initial dinner read failure on the candidate and link path, and
any manual-recipe read, store or write failure, in ErrGroundFailed so the
handler logs only reason=ground_failed and the dinner id, never database
text. Not-found, archived and conflict answers stay distinct.

Strengthen TestFixInFlightKeepsMemberEdits: start from populated method,
minutes and difficulty, edit each in flight in turn, and require the edit
kept and the untouched populated fields replaced by the recipe's values.

+  "Beef stew"); a link that names nothing is 400 — add it by name. A name
+  is trimmed, at most 120 characters and must keep a word after
+  `harness.Normalize`, which sets `normalized_name`. A name
+  `harness.Similar` to an unarchived dinner's, or a link one already has
+  (the source_url of the recipe it is grounded in, else its pasted

+- Dinner grounding. `POST /api/v1/dinners` also enqueues a `ground_dinner`
+  job and answers with its `grounding_job_id` without waiting for it
+  (`GET /api/v1/jobs/{id}` reports it); if the job cannot be enqueued it
+  still answers 201, with grounding_status `failed` (`grounding_error`)
+  and `grounding_job_id` null. The job grounds the dinner's
+  `recipe_url` directly with `GroundURL`, else its name with `Ground`
+  (see Recipe grounding), and sets grounding_status `grounded` with the
+  recipe's recipe_id, photo_id, method, minutes_total and difficulty, or
+  `failed` with `grounding_error` — also the job's failure code — one of
+  `no_recipe_found`, `recipe_unusable` (the pasted link), `search_not_configured`,
+  `search_failed`, `ai_failed`, `interrupted` (the server stopped) or
+  `grounding_error`. Each job carries the dinner's `grounding_revision`
+  from when it was enqueued; renaming a `pending` dinner clears its
+  `recipe_url`, raises the revision and enqueues a job for the new name.
+  A job for a dinner archived, no longer `pending` or at another revision
+  does no work, and a job only writes a dinner still unarchived, `pending`
+  and at its revision, so a fix-up made meanwhile wins and an earlier job
+  for an old name — queued or running — never decides the outcome.
+  Archiving or renaming a dinner also stops its running job where it is,
+  so no further search, page fetch, photo download or model call is made
+  for it. A
+  method, minutes_total or difficulty a member saved while the dinner was
+  `pending` is kept; grounding fills only those left empty. At boot, after
+  the job runner fails the jobs a previous process left running, every
+  unarchived dinner still `pending` with no `ground_dinner` job for its revision
+  queued or running is set `failed` with `interrupted`, so no dinner stays
+  pending with nothing left to ground it.
+  `GET /api/v1/dinners/{id}/recipe-candidates`
+  searches for the dinner's name and returns `{candidates: [{candidate_id,
+  title, site_name, photo_url, minutes}]}`, at most 3, ranked as `Ground`
+  ranks them; it fetches pages but downloads no photo and runs no model,
+  so `photo_url` is set only for a page already stored, and `candidate_id`
+  is the page's URL. `POST /api/v1/dinners/{id}/ground` takes exactly one
+  of `{candidate_id}`, `{recipe_url}` (both grounded with `GroundURL`,
+  setting `grounded`) or `{manual: {ingredients[], steps[], minutes,
+  method}}` (1–100 ingredient lines, up to 100 steps, each non-blank and at
+  most 500 characters; minutes 1–1440). A manual recipe is stored as typed
+  — no model runs — as a `recipes` row whose source_url is
+  `mealquest:manual:{recipe_id}` and whose raw_jsonld is a schema.org
+  Recipe built from it, and sets `manual` with its method and minutes, no
+  photo and the dinner's difficulty unchanged. Either clears the dinner's
+  pasted `recipe_url`: the recipe chosen replaces it. It answers 200 with
+  the dinner; an invalid body is 400, an unknown dinner 404, a page that cannot
+  ground it 422 `ungroundable` (the dinner is unchanged), recipe search not
+  set up 409 `not_configured`, a search or model failure 502
+  `search_failed` / `ai_failed` (only the reason code is logged, never the
+  provider's text), and grounding a candidate or link that runs past 90
+  seconds (fetch, photo and `normalize_recipe`, all in the request) 504
+  `ground_timeout`, leaving the dinner unchanged. An archived dinner is 409
+  `dinner_archived`. A candidate or link is written only if the dinner is
+  still as it was before grounding began: one renamed or grounded some
+  other way meanwhile is 409 `ground_conflict`, and one archived meanwhile
+  409 `dinner_archived`, either leaving the dinner unchanged. A method,
+  minutes or difficulty a member edits meanwhile is kept over the recipe's.
+  Any other failure grounding a candidate or link, or recording it on the
+  dinner, is 500, logged with a fixed reason and the dinner id only —
+  never the link, which can carry a personal token, or dependency error

+`web/src/dinners/letterFolds.json`, which `gen_folds.py` writes from the

+button sends `PATCH /api/v1/settings/household` with
+`{"onboarding_completed": true}`; the server sets `onboarding_completed_at`
+to the time of that update (keeping the first time if it is already set;
+the field itself is read-only and `false` is refused) and the app goes Home.
+Completing needs at least three Regulars (`household.MinRegulars`); with
+fewer the server answers 400 `invalid_settings` naming
+`onboarding_completed` and changes nothing. Step 3 can be reached with
+fewer — by its URL, or after another member removes a Regular — so it then
+shows the server's reason with an "Add Regulars" button back to step 2.
+Notification permission is never asked for on page load; until Feature 19
+wires Web Push, "Turn on notifications" asks for nothing. Offline on the saved pages the
+settings cannot be read (the service worker never caches `/api/v1/settings`),
+so the saved pages open as they are.
+
+Regular dinners (`/settings/regulars`) lists the Regulars from
+`GET /api/v1/dinners?status=regular`, each with its photo, "method ·
+minutes", favorite heart and grounding badge ("Finding recipe…" while
+`pending`, "Recipe found" when `grounded` or `manual`, "Needs a recipe" when
+`failed`). The add field takes a name or a pasted `https://` recipe link.
+Tapping a Regular opens an edit sheet (name, method, minutes, difficulty;
+remove archives it after a confirmation); tapping one that needs a recipe
+opens "Fix recipe" (pick one of the recipe candidates, paste a link or type
+the ingredients and steps in). Adds, removals and the heart show at once and
+are undone if the server refuses them. While any Regular is `pending`, the
+list is read again every 3 seconds (not while a change is in flight), and
+polling stops once none is.
