Add Lenovo HS10 and Dr.Trust SSW526 support

[RealBhupesh]

What changed

• Add Lenovo HS10 support for the FFF0/FFF1/FFF4 history stream, including F2 00 history requests, ten-byte timestamp/weight/impedance decoding, duplicate protection, and consumed-history cleanup.
• Add Dr.Trust SSW526 support for the AC 27 FFB2 stream, including the captured offset-weight decoding, fixed-frame validation, stability detection, and weight publishing.
• Route both device-specific handlers before the generic MGB handler and narrow SSW532 matching so SSW526 is not misclaimed.
• Add focused protocol and handler-recognition tests.

Why

Issue #1437's HS10 capture showed the device's FFF0 service with FFF1 write and FFF4 notify characteristics but no measurement packet. The implementation follows the compatible HS11 packet reference and keeps the unverified hardware assumption explicit.

Issue #1436's SSW526 capture showed repeated AC 27 frames that the existing MGB/Taylor parsers ignored, so no measurement was published.

Validation

• git diff --check and committed-diff checks pass.
• Focused and full Gradle test commands were attempted, but local compilation is blocked because this checkout has no Android SDK/local.properties configured.
