fix(hub): rewrite initial migration to match the ORM models

Six columns (users.pw_version, users.pk_node_ed25519, users.role,
groups.description, refresh_tokens.family_id) and two tables
(notifications, hub_peers) were never created by migrations — they
relied on create_all(), which creates missing tables but never a
missing column. This passed every test (fresh SQLite each run) and
broke every deploy to a wiped PostgreSQL database.

One migration now creates the complete schema. The seven incremental
files are removed; their changes are folded into the initial schema.
Safe on a fresh database only, which is the only case that exists
after the meshbay.org wipe.
