refactor(server): squash drizzle migrations 0000-0004 into single baseline

Generated by pnpm db:generate against the current schema.ts — replaces
five historical migrations (0000_initial, 0001_clear_earthquake,
0002_peer_approval_requests, 0003_classy_loki, 0004_cooing_black_knight)
with one baseline that matches the schema shape all five produced together.

Pi + VM __drizzle_migrations rows will be rewritten per the Phase 2
surgery procedure before this deploys to either instance; DBs already
match the new baseline, no DDL runs. Phase 1 audit verified no still-present
bugs depend on any of the squashed migrations.

Refs backlog #31 Phase 2.
