Add the dinners API for Regulars

POST /api/v1/dinners adds a Regular from a name or a recipe link
(status and origin regular, grounding_status pending), refusing a name
harness.Similar to an unarchived dinner, or a known link, with 409.
GET /dinners?status=regular|quest_log lists dinners with photo URLs and
grounding status; PATCH /dinners/{id} edits name, method, minutes and
difficulty; DELETE archives the row; POST /dinners/{id}/favorite toggles
is_favorite. Every write records the session subject as updated_by.

Migration 0008 adds dinners.recipe_url so a pasted link is kept until
grounding resolves it.
