First step of decoupling artist identity/storage/display. migration 0077 drops uq_artist_name so the display name is free text (two genuinely different creators can share a name); the slug stays the immutable, unique storage/identity key (the on-disk path component — untouched, so nothing moves). ArtistService.rename + PATCH /api/artists/<id> change the name ONLY. Frontend: inline pencil-edit on the artist header (mirrors TagCard), slug/route unaffected so no navigation. Fixes the operator's 'no surface to rename an artist' + the name-collision fragility.

Artist model fragility fix (milestone #130). One `slug` column was doing
|
|
identity + storage-path + display, and BOTH `name` and `slug` were UNIQUE, so
|
|
the display name couldn't be edited freely and two genuinely different creators
|
|
collided. Decouple: `slug` stays the immutable, unique storage/identity key (the
|
|
on-disk path component — untouched here); `name` becomes freely editable, NON-
|
|
unique display text. This migration only drops the `uq_artist_name` constraint;
|
|
no data moves and no path changes.
