feat(db): switch to @clawnify/db dual-binding adapter

Templates now work on both prod (Workers for Platforms + D1) and
preview (Dynamic Workers Facet via env.STORAGE). The shared adapter
in @clawnify/db detects the binding at runtime; no template-side
branching needed.

Fixes the 'Cannot read properties of undefined (reading prepare)'
error on <slug>.draft.clawnify.com where env.DB is not bound.
