Make recipe repairs conditional and keep pasted links out of logs

F1: A candidate or link repair now writes the dinner only if it is still
unarchived and as observed before grounding (normalized_name,
grounding_status, grounding_revision and recipe_id). A dinner renamed or
grounded some other way meanwhile is ErrGroundConflict (409
ground_conflict); one archived, before or during the repair, is
ErrArchived (409 dinner_archived). Manual repairs reject archived dinners
too.

F2: Any failure grounding a candidate or link by hand wraps
ErrGroundFailed, which the API logs as reason=ground_failed with the
dinner id only, never the pasted link or dependency error text.
GroundURL no longer formats the link into its error.
