fix: keep Drizzle out of every published declaration (ADR 0053)

@ekklesia/contracts still emitted a type-only import of
drizzle-orm/node-postgres for the legacy ModuleDatabase facade, so a
standalone module type-checked only because skipLibCheck hid it.

- ModuleDatabase, LegacyModuleRuntimeServices and
  AnyModuleRuntimeServices move to core/src/modules/database.ts, beside
  the facade Core builds; the facade itself is unchanged.
- contracts' runtime, route, and services generics no longer name an
  ORM: the database type is a plain parameter defaulting to the ABI v1
  executor, and the legacy definition's database is opaque until Core
  specializes it. Core and apps/api name the legacy types from Core.
- contracts drops its drizzle-orm optional peer and devDependency;
  Drizzle stays public only through @ekklesia/module-database/drizzle.
- The facade's type-level test moves from contracts to Core.
- Regression proof: the standalone fixture type-checks with
  skipLibCheck: false against the packed tarballs, with no drizzle-orm
  installed (the smoke asserts both). Against the previous contracts
  tarball the same check fails with TS2307 on drizzle-orm/node-postgres.
