Fix easyEnergy price period count sensor semantics

[klaasnicolaas]

Proposed change

The two hours_priced_equal_or_* sensors expose counts from python-easyenergy, but currently label them as hours. Remove UnitOfTime.HOURS and rename their translated display names to “Periods priced …”. No device class applies: these values count today's periods whose usage price is at or below the current usage price, or whose return price is at or above the current return price. The library counts matching intervals without weighting their duration.

Keep the existing entity IDs, unique IDs and translation keys. The current hourly request granularity and numeric values are unchanged. The incorrect unit_of_measurement: h attribute is removed. Tests cover state, unit, device class, names and identity, plus inclusive comparisons with distinct usage/return prices for hourly and quarter-hourly data.

🔵 Needs a closer look

It changes user-facing sensor metadata/semantics (removing a unit of measurement) that normally warrants code-owner review, and the test outcomes depend on python-easyenergy behavior that could not be executed in this environment.

Pull request overview

This PR corrects the semantics of the two easyEnergy "priced equal or lower/higher" count sensors. These sensors return a count of matching price periods from python-easyenergy, but were incorrectly labeled with UnitOfTime.HOURS and displayed as "Hours priced …". The fix removes the misleading unit and renames the display strings to "Periods priced …", while intentionally preserving the existing entity IDs, unique IDs, and translation keys to avoid breaking users. It fits into the broader effort to raise this integration to Platinum quality (related PR #181378).

Changes:

• Remove native_unit_of_measurement=UnitOfTime.HOURS (and the now-unused UnitOfTime import) from the two count sensor descriptions.
• Rename the two sensor display names in strings.json from "Hours priced …" to "Periods priced …" (translation keys kept as hours_priced_*).
• Update existing sensor tests for the new names/absent unit, and add a parameterized test_price_period_counts covering inclusive counting for distinct usage/return prices at hourly and quarter-hourly granularity.

File summaries

File	Description
homeassistant/components/easyenergy/sensor.py	Drops the incorrect UnitOfTime.HOURS unit and its import from the two period-count sensors.
homeassistant/components/easyenergy/strings.json	Renames the two sensor display names from "Hours priced …" to "Periods priced …".
tests/components/easyenergy/test_sensor.py	Updates existing assertions (unit absent, new names) and adds a parameterized test verifying inclusive period counts across interval sizes.
