Logging via print() in QML-reachable code paths is invisible in the app console

[rozyczko]

Source: multiple — DEEP_ANALYSIS.md §5 item 19

Several QML-reachable paths log via bare print(), which is invisible in the app's console/logging framework used everywhere else:

• analysis.py:1022, 1085, 1146
• sample.py:1093, 1153
• logic/experiments.py:89-91, 100, 106
• logic/parameters.py:228-231

Fix: Replace print() with the standard logging/console mechanism used elsewhere in the codebase.
