fix: council-review noise cuts — scenes/central-macros exempt, language-matched repairs

External expert review (real run on the demo house) flagged: scenes (18.001)
wrongly marked missing_status + an unsafe DPT-1.011 status repair for them;
'All blinds down' warned while 'All lights off' was correctly INFO; and a Russian
'(статус)' suffix synthesised on an English project. Fixes: scene_no_status INFO
+ no synth status for scenes; broadened central-macro detection (generic 'all
blinds/shutters/...'); language-matched repair suffixes. Demo missing_status
warnings ~7 -> 1 genuine. tests/test_council_fixes.py; full suite green.

 ### Fixed
 
+- **Noise & unsafe repairs surfaced by an external expert review on the demo house.** (1) Scene-control
+  GAs (DPT 17/18) are no longer flagged as `missing_status` — they recall a preset and have no single
+  state to read back (now `scene_no_status`, INFO), and `suggest_repairs` no longer synthesises a bogus
+  boolean status GA for them. (2) Generic group commands (`All blinds down`, `All shutters up`) are now
+  recognised as central macros (INFO) like `All lights off`, not missing-status warnings. (3) Synthesised
+  repair names match the GA's language — an English project no longer gets a Russian `(статус)`/`Значение
+  яркости` suffix. On the demo house this cut `missing_status_address` warnings from ~7 (mostly scenes) to
+  the one genuine case. `tests/test_council_fixes.py`.
+
 - **`skills/ha-git-backup`**: `install.sh` now pins `core.sshCommand` + a repo-local `known_hosts`
   so the nightly sync pushes from HA's Core container (was failing `Host key verification failed`).
