task: #3621015 Back to DEV

Back to DEV after 1.0.0-beta1 was tagged and released.

• composer.json version -> 1.0.x-dev.
• The sixteen drupal/varbase_*_base cross-dependencies and drupal/vartheme_bs5_horizonaid -> 1.0.x-dev.

The released constraints (~1.0.0-rc4, ~1.0.0-rc1, ~1.0.0-alpha4 and so on) belong on the release tag, where they pin what a user actually installs. The dev branch tracks its sibling dev branches, so work in progress across the Varbase recipes and the Horizon Aid theme is picked up here rather than being held back to the last published release.
