Add Drizzle/Neon Postgres schema for collections, urls, and collectio…

[ebulgakov]

…n_items

Introduces the core data layer: per-user collections of URLs joined many-to-many via collection_items, with a case-insensitive unique collection name per user, a persistent shareable slug, and per-user URL dedup on a stored normalized_url column. collections.user_id and urls.user_id FK across schemas into Neon Auth's neon_auth.user(id), which is declared reference-only (not exported from schema.ts) so Drizzle Kit never tries to manage that table.
