Add ble-scale-sync

[KristianP26]

Adds ble-scale-sync as the last item under Apps > Third Party Apps.

Re-submission of #642, which was closed on the 6-month repository-age rule with an invitation to return after 2026-07-13. The repo was created 2026-01-13, so it is now 7 months old.

What it is: a headless bridge that reads weight and body composition (fat %, muscle mass, bone mass, water %, BMR, visceral fat and more) from 25+ Bluetooth smart scale brands, and publishes all 11 metrics over MQTT with auto-discovery. Sensors appear automatically as one grouped device, with LWT availability and per-metric display precision. Multi-user support matches a reading to the right person by weight, so a shared scale produces separate device entries.

It ships as an installable app via its own repository (repository.yaml + ble-scale-sync-addon/), with MQTT credentials auto-detected through the Supervisor API, which is why Third Party Apps is the right section rather than DIY.

Acceptance criteria:

• Not archived, actively developed (v1.23.0 released 2026-08-19, releases roughly monthly).
• Created 2026-01-13, over 6 months old.
• README.md at the repository root, in English.
• GPL-3.0, OSI-approved.
• 153 stars, well above the 10-star soft bar.
• README mentions Home Assistant.
• Documentation site: https://blescalesync.dev

Self-promotion disclosure: I am the author, so CI will flag this. The case for inclusion: there was no open-source way to get a generic BLE body-composition scale into Home Assistant without the vendor cloud app. It covers 30 protocol adapters across brands such as Xiaomi, Renpho, Beurer, Eufy, QN, Yunmai and Arboleaf, works over built-in Bluetooth, an ESPHome BLE proxy, or an ESP32/MQTT proxy, and about 20 of the supported scales were added from user-submitted captures. There is also a community Home Assistant integration built on top of it (JustBeanie/ble-scale-hass).
