Adds POLAR_H10_BOARD (73) using SimpleBLE. The default preset contains 130 Hz ECG in microvolts, the PMD device clock and a preparation-time battery reading. The auxiliary preset preserves every HR/RR event, including multiple RR intervals in one notification; it explicitly declares an irregular sampling rate of 0 rather than representing the events as a uniform waveform.

The driver selects an advertised H10 by optional address/device ID, subscribes to control indications or notifications according to the characteristic, checks the 130 Hz/14-bit ECG settings, validates multipart PMD responses, and waits for both a successful START acknowledgement and ECG data. Errors, missing replies and cleanup are covered through a transport seam using the actual driver lifecycle. All binding IDs and documentation are aligned.

Validation: warnings-as-errors Linux build; all 67 native tests pass, including Polar's published signed ECG fixture, settings and HR/RR parsing, control rejection, missing responses, first-data timeout, stop/restart and release/reprepare. These tests are part of the existing native CI suite. BLE discovery/subscription timing and physical H10 operation remain unverified; accelerometry, compressed frames, offline recording and other Polar models are outside this PR.

Reference: official Polar BLE SDK.
