fix: remove .lance-reserved marker after writing table in namespace mode

lance v6.0.0-beta.2 introduced a `.lance-reserved` marker file in
declare_table to prevent directory scans from seeing incomplete tables.
lancedb calls declare_table to get the canonical URI, then writes data
separately via NativeTable::create_from_namespace, but never cleaned up
the marker. This caused list_directory_tables() to skip tables with the
marker, making newly created tables invisible in table_names().

After writing the table, delete the marker using the dataset's configured
object store so it works for both local and cloud storage.
