refactor: extract object store into dedicated crate with filesystem backend (#7996)

* refactor: extract object store code into windmill-object-store crate with filesystem backend

Consolidate all object_store-dependent code from windmill-common into a new
windmill-object-store crate. Add a filesystem-backed object store implementation
using LocalFileSystem for dev/testing without cloud credentials. Includes 30
comprehensive tests covering render_endpoint, lfs_to_object_store_resource,
duckdb_connection_settings, error mapping, and filesystem-backed integration tests.
