Casey 7c565a5f5f Fix options-flow conditional reveal + empty lux-sensor save ... Two config-flow bugs in the Ambient lux / Advanced sections: - Conditional fields (target_lux, send_split_delay) only appeared on a fresh re-open of the dialog, never in the same session — violating the options-flow spec ('SHALL re-render ... in the same session'). Now, when a driver is enabled but its dependent field was hidden from the rendered schema, the form re-renders (carrying the user's edits) instead of saving. - The options form could not be saved at all without selecting a lux sensor: vol.Optional(CONF_LUX_SENSOR, default='') fed '' into the illuminance EntitySelector, which rejects empty strings. Omit the default (vol.UNDEFINED) when no sensor is configured. Extracted _has_pending_reveal() and _overlay_range_values() helpers to keep async_step_init under the branch limit. Added 3 flow-level tests exercising the real re-render path (prior tests only hit the schema builder, which is how these slipped through). 141 tests pass.		2026-05-30 22:06:59 +02:00
