neon a06b111046 feat(reader): merge reader settings field by field over PATCH
PUT reader/defaults/:formatGroup demands the full settings object, so a client has to send every
field of a group to change one of them. That forces a client to own fields it does not model and to
echo back values it never shows, and it turns two clients editing different fields into a
last-writer-wins race over the whole row.

Add PATCH for both defaults and per-book preferences. The defaults patch merges over the stored
row with the built-in defaults folded in underneath, so the row stays a complete object for the web
client's sanitiser while a partial caller leaves no holes. The per-book patch takes set and unset
and resolves both in one statement, so a concurrent patch cannot lose a field to a read-modify-write,
and deletes the row once its last key goes, which is the same state as never having been customized.
Nulls are never stripped: a null fontFamily means "use the book's own font", not an absent key.

Keep only the keys the caller actually sent. Zod applies .default() while parsing a partial, so a
cbx patch that never mentioned spreadGap came back carrying one; the existing per-book PUT had the
same latent bug and now shares the fix, which stops a touched comic from being pinned to the
default gap.

iOS is the only caller of the new routes. It keeps the layout fields on the device and syncs the
look fields, which is exactly the split a partial write makes expressible. The web client does not
call them and still PUTs full snapshots.
