v2.4.0-cdit.1 — lower/upper sliders + new defaults

Changed

• Range sliders renamed: Min/Max brightness → Brightness lower/upper, Min/Max color temp → Color temp lower/upper. The HA device page sorts entities alphabetically by name, so each quantity's lower bound now lists above its upper bound (previously Max always sorted above Min).
• Entity_ids are unaffected: existing profiles keep their registry entity_ids; new profiles pin suggested_object_id to the field keys, so they still slug number.<profile>_min_brightness etc. Automations need no changes.
• New-profile defaults: brightness 10–90 % (was 5–100 %), color temp 2000–5500 K (was 2200–5500 K). Existing profiles keep their saved values.

Internal

• Lint is fully green: ruff target bumped to py312 (matches requires-python), all remaining ruff errors fixed or explicitly noqa'd with justification.
• Specs synced (runtime-range-controls, output-sensors); two new tests cover the slug pin and name composition.
