Initial scaffold for AvtoAmbor parts inventory

SvelteKit 2 + Svelte 4 + adapter-node, SQLite via better-sqlite3 (WAL,
foreign keys on). Bilingual EN/Тоҷикӣ throughout, locale persisted in
localStorage.

Pages: dashboard (totals, low stock, recent movements), parts list with
search and sort, part create/edit, record movement (in/out/adjust with
smart unit-price and adjust-quantity prefill), suppliers list with
inline add.

Schema: categories, suppliers, parts (with _en/_tg name+description
columns, dirams for money), stock_movements with check on movement_type.
On-hand updates are done in JS inside a transaction with the movement
insert.

Dockerized dev: docker compose, named project, bind-mounted data/ for
DB persistence. Seed contains 6 categories, 4 suppliers, 31 realistic
parts (Lada / Nexia / Opel / Toyota bias).
