Track iOS HealthKit sensors for local health package

[CCOSTAN]

Context

Split out from #1815 item 1 so this can be tracked independently.

Upstream Home Assistant iOS work: home-assistant/iOS#4923

As of 2026-07-04, the upstream PR is open and draft. It proposes optional Apple HealthKit-backed Companion App sensors exposed through the existing sensor webhook flow, with per-sensor controls. The relevant local opportunity is to consume the final iOS health sensor entities once they are merged and released.

Proposed local direction

• Track the upstream PR, companion app release notes, and documentation until HealthKit sensors are merged and available.
• After release, verify the actual Home Assistant entity IDs and attributes from the live Companion App integration before adding YAML.
• Add a local health package for daily movement and resting-heart-rate helpers using the final sensor names.
• Consider Telegram coaching automations and optional health-note or memory summaries only after the base sensors are stable.
• Keep public docs and GitHub comments privacy-safe; document patterns and derived helper behavior, not private health details.

Acceptance criteria

• Upstream HealthKit sensor support is merged and available in an iOS Companion App release.
• Live HA entities for the enabled HealthKit sensors are verified before implementation.
• Local package uses the standard YAML header and keeps helpers centralized in the relevant package file.
• Daily movement/resting-heart-rate helper behavior is implemented with stable, recorder-friendly sensors where appropriate.
• tools/ha_check_config.ps1 passes after any local YAML changes.
• Relevant package README/docs are updated if local behavior changes.

Closing this as not planned. The HealthKit workflow has been rolled out using HealthKit Auto Exporter, and the proposed native Home Assistant Companion App sensors do not provide anything we do not already have. No further local package work is needed here.
