Expose Heiman smoke and CO sensor sirens as siren entities

[TheJulianJES]

DRAFT / EXPERIMENTAL.

Proposed change

The Heiman HS1SA-E-Lover, HS1SA-E-PLUS, HS1CA-E-PLUS and HM-722ESY-E-PLUS expose a manufacturer-specific siren_for_automation attribute (cluster 0xFC90, attr 0x0012) that sounds the siren until cleared, with a selectable smoke/CO tone. The device also resets it to Stop on its own after a timeout.

Today these quirks expose the IAS WD siren, which is fixed-tone and limited by ZHA to ~30 s. This PR replaces it with an attribute-controlled siren via a new QuirkBuilder.siren() method, so the siren is tone-selectable and sounds until turned off — and it reuses the IAS WD siren's unique_id ({ieee}-1-1282) so existing entities migrate rather than orphan.

Builder API additions

• SirenMetadata (zhaquirks/builder/metadata.py) — attribute_name, available_tones ({value: name}), off_value, default_tone.
• QuirkBuilder.siren(...) (zhaquirks/builder/builder.py) — exposes a siren backed by writing an attribute.
• discovery (zhaquirks/builder/discovery.py) — maps (SIREN, SirenMetadata) → ZHA's siren.AttributeSiren.

Per-quirk changes (all four files)

• Dropped .exposes_feature(SIREN_BASIC) and the .change_entity_metadata(IasWd …) demotion.
• Added .prevent_default_entity_creation(endpoint_id=1, cluster_id=IasWd.cluster_id) to suppress the default IAS WD siren.
• Added .siren(..., unique_id_suffix="1282") with tones {Smoke siren, CO siren}. Default tone = smoke for the smoke sensors, CO for the CO sensors.

The IAS WD cluster itself is kept (only its siren entity is suppressed).

Additional information

• Depends on Add attribute-controlled siren entity for quirks v2 zha#816, which adds the AttributeSiren entity + EntityPlatform.SIREN this PR imports. This PR's CI won't pass until that lands and releases; tone selection in the UI additionally needs the small HA Core change described in that PR. Siren on/off + state work with zha + this PR.
• Possible restructure: AttributeSiren could instead live in this repo (subclassing ZHA's BaseSiren), keeping only EntityPlatform.SIREN in ZHA. See the "Open question" section of Add attribute-controlled siren entity for quirks v2 zha#816 — it's a maintainer call and would move code from that PR into this one.
• Translations: translation_key="siren" is a new key (no entity.siren section exists in ZHA's HA strings.json yet — this would be the first). Tone values ("Smoke siren" / "CO siren") are not translated by HA — siren tones render raw, so human-readable names are used (matching the existing "Burglar"/"Fire" tones). A co_siren slug would show literally as co_siren; if translated tone labels are wanted, a select entity is the alternative (details in the ZHA PR).

Device diagnostics

No new diagnostics snapshots are required: none of the four affected models has a snapshot in ZHA's tests/data/devices/ (the existing heiman-smokesensor-em.json is the unrelated legacy v1 SmokeSensor-EM), so there's nothing to regenerate. The custom clusters and models are unchanged from the already-merged quirks.

Checklist

• The changes are tested and work correctly
• pre-commit checks pass / the code has been formatted using Black
• Tests have been added to verify that the new code works
• Device diagnostics data has been attached
