feat: SDK surface for functions, materialized views, jobs, refresh_column

Adds the derived-compute interface to the SDK:

- Database trait: create/list/drop_function, create/refresh/alter/
  drop/list_materialized_view, list_jobs -- default implementations
  return Error::NotSupported (NotImplementedError in python), so
  existing Database impls are unaffected; local single-node
  implementations are planned. BaseTable gains refresh_column with
  the same default.
- RemoteDatabase/RemoteTable implement them against the server REST
  routes (/v1/function/*, /v1/materialized_view/*, /v1/job/list,
  /v1/table/{id}/refresh_column), with mock-HTTP unit tests.
- Connection/Table public methods, pyo3 bindings (FunctionInfo,
  MaterializedViewInfo, JobInfo pyclasses), and python wrappers:
  sync on the DBConnection base (shared by local and remote
  connections), async on AsyncConnection; refresh_column on
  LanceTable, RemoteTable, and AsyncTable.
