V153: folder header size defaults to small.
New folders now open with a small hero header (see the schema default on
PhoenixKit.Modules.Storage.Folder). This migration brings existing rows
and the DB column default in line:
Column default
phoenix_kit_media_folders.header_sizeflips from'medium'(set in V134) to'small', so raw inserts match the changeset default.Backfill every folder currently on
'medium'→'small'.'medium'was the old default, so a stored'medium'is indistinguishable from "never touched" — those reset to small.'large'was never a default, so any'large'is a deliberate choice and is left alone; existing'small'rows are unaffected.
There is no stored "user customised this" signal, so a folder someone
deliberately set to 'medium' also resets — an accepted trade-off, since
medium and default-medium can't be told apart. Users can re-pick medium
from the header-size control any time.
Idempotent: the backfill's WHERE header_size = 'medium' and the default
swap are safe to re-run.
