chore(deploy): pin dictionary seed to v1.3.0

Bump DICT_VERSION v1.2.1 -> v1.3.0 across the seed surface: .env.example, the
compose build-arg default, both backend Dockerfile stages, the loadtest
Dockerfile, the CI dawg-download version, and the deploy/backend docs.

v1.3.0 drops the abbreviation class from the Russian word list (scrabble-dictionary
#6). This only seeds a FRESH volume; a live contour/prod volume is unaffected (the
.seed_version marker wins — seed-drift guard) and moves to v1.3.0 through the admin
console (ARCHITECTURE §5). Per-contour deploy still overrides via TEST_/PROD_DICT_VERSION.
