fix(datomic): install tuple attributes after the attributes they compose

Browse Source 
A composite tuple can only be created once its member attributes exist, and the
pieces are split across the two schema files: the tuple
:journal-entry-line/running-balance-tuple is declared in schema.edn while one of
its members, :journal-entry-line/running-balance, is declared in
cloud-migration-schema.edn, which is transacted afterwards.

Against a long-lived database this never surfaced, because those attributes were
installed by separate transactions years apart. Against an empty one it fails
outright with :db.error/invalid-tuple-attrs, which meant transact-schema could
not build a fresh database at all — and since every test fixture starts from an
empty datomic:mem database, the entire test suite died in setup rather than in
any individual test.

Install every plain attribute first, then every tuple.

A tuple can only be created once the attributes it composes already exist, and the pieces are
spread across both files — `:journal-entry-line/running-balance-tuple` lives in schema.edn
while one of its members, `:journal-entry-line/running-balance`, lives in
cloud-migration-schema.edn. Transacting the files in order therefore cannot install that tuple
against an empty database. Long-lived databases never hit it because those attributes went in
years apart."
