Do not set the generic heart-rate entry to chestStrap.

kBleHrs matches any device that advertises the Heart Rate service, including armbands and watches. Its kind: DeviceKind.chestStrap puts those devices under the chest-strap filter and shows strap-specific text when they pair without a band. Use a kind that does not assume a chest strap, or derive the kind from the device.

Review comment at @lib/ble/adapters/_registry.dart at line 724:
Update the kind assigned to kBleHrs so it does not classify every device
advertising the Heart Rate service as a chest strap; use a neutral device kind
or derive the kind from the device.

Leaving this one. chestStrap for the generic heart-rate entry is deliberate: the registry bans DeviceKind.other for entries (test/ui2_pairing_blocks_test.dart), and in practice the devices that pair through ble_hrs are overwhelmingly straps. An armband still pairs and works; it just sits under Straps in the filter.

@mikenrafter Understood. kBleHrs will remain under Straps, including for armbands. Thanks for explaining the trade-off.
