feat(uload): rewrite to local-first + Hono architecture

- Move from apps-archived/ to apps/
- Delete NestJS backend, PocketBase, old scripts and docs
- Create Hono/Bun redirect server (click tracking, analytics API)
- Create @manacore/uload-database shared Drizzle schema package
- Add local-first store (Dexie.js) for links, tags, folders
- Rewrite Links and Tags pages to use IndexedDB
- Simplify hooks, layouts, remove all server-side data loading
- Add dev scripts: dev:uload:web, dev:uload:server, dev:uload:local
