Apply language settings from _common.yaml in slot combination tests

[parkghost]

Important

CI fails here by design, and the failure is the point. With settings applied, the two English search_query examples currently on main are exposed as asserting a value that never occurs in Home Assistant:

FAILED test_HassMediaSearchAndPlay_name_only[zh-TW]
FAILED test_HassMediaSearchAndPlay_area_media_class[zh-TW]
2 failed, 260 passed

Those two examples are corrected in #4026. Once that lands, this PR goes green with no changes needed here. Marked as draft until then.

Changes

lang_resources (tests/test_slot_combinations.py:132) builds its intents dict by hand and reads only skip_words from _common.yaml, so settings is dropped. As a result 8 languages are tested under a configuration Home Assistant never uses:

languages	declared in _common.yaml	tested as
zh-CN zh-HK zh-TW	ignore_whitespace: true	false (hassil default)
cs de ne nl vi	filter_with_regex: false	true (hassil default)

The same sentence can therefore resolve to different slot values here and in the packaged data. 在電視上播放 Taylor Swift gives search_query='Taylor Swift' in this repo's tests but 'TaylorSwift' in the intents-package sanity check, which loads the exported JSON where settings is present. That divergence is what #4026 had to work around.

common_dict is already loaded on the preceding line, so the fix is to read settings from it as well:

lang_intents_dict["skip_words"] = common_dict.get("skip_words", [])
lang_intents_dict["settings"] = common_dict.get("settings", {})   # added

Worth noting why this stayed invisible: dropping settings only ever makes tests more permissive, never red. No existing test sentence can tell the two configurations apart — flipping ignore_whitespace to false for all three Chinese languages leaves them at 712 passed. The behaviour it protects (input containing spaces, e.g. 打開 大燈) has no test coverage at all.

The underlying wildcard behaviour that this exposes is reported upstream in OHF-Voice/hassil#276.

Testing

Verified on top of #4026:

• python3 -m script.intentfest validate (all languages) — All good!
• pytest tests -n auto — 14662 passed

No language changes behaviour under the corrected configuration.

Once #4026 is merged this PR turns green as-is — it is based on main rather than stacked, so no rebase is needed. Only two things are required at that point: re-run CI and mark this ready for review.

Feel free to do both yourself if you get there first, or ping me and I will.
