test: expand gtest coverage for common/core utilities

Add unit tests for: - CommandLineParser, Debug handler, Decibel, Digit, JobTime, FFmpegUtils - Core StringUtils, Timecode, TimeRange, Bezier, Color - Extend Frame tests to cover pixel access, interlace, conversion Coverage improvements (app + ext/core): - commandlineparser.cpp: 0% -> 93% - debug.cpp: 0% -> 85% - decibel.h: 25% -> 88% - digit.h: 0% -> 100% - ffmpegutils.cpp: 29% -> 90% - frame.cpp: 53% -> 97% - bezier.cpp: 16% -> 98% - color.cpp: 13% -> 71% - Overall line coverage: 17% -> 19%
