Reject malformed search bodies and report unranked candidates

SearXNG now requires a results array and Brave requires "type": "search"
with a results array in any web object, so `{}` is ErrSearchResponse
instead of an empty search. Rank no longer drops failed candidates: it
returns the ranked ones with ErrCandidatesUnranked joined with each
unranked candidate's URL and reason, or ErrNoUsableRecipe when none rank.
Adds an HTTPS ranking test through the SSRF-safe Fetcher.

   and reason (fetch failure, no valid recipe, missing ingredients or
   image), so the caller decides per item what a failure means.
-- Ingredient lines are normalized by the `normalize_recipe` v1 skill
-  (`skills.NormalizeRecipe`), always at temperature 0 whatever the
-  household's setting. From the title, raw ingredient lines, steps and
-  JSON-LD times it returns `{ingredients: [{name, qty, unit, note}], method,
-  difficulty, minutes_total}`. Validation requires exactly one ingredient
-  per input line, in order (a name matching another line but not its own is
-  out of order), each with a name; a mismatch gets the harness's repair
-  turn. Code-derived values win: a positive JSON-LD total is
-  `minutes_total`; "slow cooker" or "crock pot" in the title or a step makes
-  the method `crockpot`; a difficulty the model leaves null is derived —
-  hard over 10 steps or 90 minutes, easy at 5 steps or fewer and 45 minutes
-  or less, else medium, a crockpot's minutes not counting.
 - Photos are cached locally (`photos`) and processed with
-  `golang.org/x/image`. `recipes.PhotoCache.DownloadPhoto` downloads through
-  the Fetcher's `FetchImage` (JPEG, PNG, WebP or GIF content types, 8 MB
-  cap, not cached), decodes the image (a GIF's first frame) and refuses a
-  decoded image under 300 px on its short side, recording nothing.
-  `CachePhoto` then records it in the caller's transaction: it scales the
-  image so its long side is 1200 px and 400 px, and stores each as JPEG
-  quality 82 at `$MEALQUEST_DATA_DIR/media/photos/{id}-{size}.jpg`. Images
-  are deduplicated by the SHA-256 of the downloaded bytes; the writer's
-  single connection serialises transactions, so one image is never
-  recorded twice. Files written for a transaction that rolls back are
-  removed by the caller (`RemovePhotoFiles`).
-- Grounding (`recipes.Grounder`) ties these together.
-  `Ground(ctx, dishName, query)` searches for the top 5 candidates and ranks
-  them all, stored and new alike: a candidate whose `source_url` is already
-  stored is scored on its stored recipe (title, ingredients, steps, times,
-  photo source) and its page is never refetched; every other candidate is
-  fetched and extracted. Ranking alone decides between them. It then tries
-  each ranked candidate best first. A stored one is returned as it is, so a
-  stored recipe is reused only when it ranks above every new candidate that
-  grounds. A new one is grounded in this order: (1) `DownloadPhoto` —
-  the download and validation step of photo caching — (2)
-  `normalize_recipe`, then (3) one **transaction** that runs `CachePhoto`
-  (scales and writes the photo files and records the `photos` row) and
-  stores the recipe, ingredients and steps (an existing `source_url` is
-  updated in place); files written for a rolled-back transaction are
-  removed. It returns `Grounded{recipe_id,
-  photo_id, method, minutes_total, difficulty, source_url, site_name}`. A
-  candidate whose photo fails or whose model output is unusable
-  (`llm.ErrBadOutput`) is passed over; when none grounds, the error is a
-  typed `*recipes.ErrUngroundable` listing every reason (no candidates,
-  Rank's per-candidate reasons, photo or normalize failures). Failures
-  that are not the candidates' — search, model provider, database — are
-  returned as they are. `GroundURL(ctx, url)` does the same for one pasted
-  URL. `GroundMany` grounds items 3 at a time and returns one result per
-  item, so one failure never affects its siblings. A recipe is usable only
-  with ingredients, an image and, if given, a positive total time.

--- 0007_recipe_grounding: a grounded recipe keeps what recipes.Ground
--- returns, so a stored source_url is reused without fetching or normalizing
--- it again: its cached photo, and normalize_recipe's method, difficulty and
--- minutes_total (prep to table; total_minutes stays the page's own JSON-LD
--- total). Nothing wrote recipes before Ground did, so the columns are added
--- nullable rather than with a default no recipe has; Ground always sets
--- photo_id, method and difficulty and refuses to reuse a row without them.
---
--- recipe_search_settings gains api_key_last4, the last four characters of
--- the Brave API key, so the settings can show which key is stored without
--- ever returning it.
