Prefix include guards for h3/linux headers

Replace generic include guards (e.g. TIMING_H_, PANELLED_H_, WATCHDOG_H_, SERIALNUMBER_H_) with more specific names prefixed by H3_ or LINUX_ to avoid macro collisions when both lib-h3 and lib-linux headers are included. A minor formatting tweak was also applied to the Millis() inline signature (added space after attribute). No functional changes intended.
