FavoriteLink existed in schema.prisma but was never captured in a
migration -- same bug class as the DashboardLayout fix in
20260629130000_add_missing_tables. It silently worked in local dev
(table created via db push) but any environment relying on
`prisma migrate deploy` never got the table, causing every
GET /favorites request to 500 with PrismaClientKnownRequestError
P2021 ("table does not exist").
Found live testing the production deploy at alpha.tessera.ctl.de:
adding a Favoriten widget triggered the 500. Confirmed via server
logs (docker logs) and by inspecting _prisma_migrations / \dt on
that database.
CREATE TABLE/INDEX IF NOT EXISTS makes this safe to apply against
environments where the table already exists untracked (verified: ran
clean against local dev's DB, which already had the table from a
prior db push, with zero errors and zero data loss).
