* feat(operator): allow last_row merge_mode when append_mode is enabled - Update RegionOptions::validate to allow last_row merge_mode with append_mode. - Update fill_table_options_for_create to automatically set merge_mode to last_row when append_mode is enabled for LastNonNull table type. - Add unit tests in mito2 and operator to verify options validation and table creation. - Add integration test for InfluxDB write with append mode hint. Signed-off-by: Lei, HUANG <mrsatangel@gmail.com> * fix(operator): simplify append mode options Group `LastNonNull` auto-create options in a single append-mode branch.
