Bumped version from 1.0.5 → 1.0.6 (src/meritscalc/version.py).
Switched some relative imports to package-qualified imports in the main entry (improves reliability when run as an installed package): from .logic/.qt_ui/.settings → meritscalc.logic/meritscalc.qt_ui/meritscalc.settings.
About tab UI refactor (tighter margins/spacing, adjusted fonts, compact description, developer/version inline row, smaller app icon 150→120 px, consistent button sizes and spacing).
Renamed "Open Source License" → "License" in About buttons and tightened button styling.

Fixed / Improved:

Improved module resolution for certain entry points by using package-qualified imports.

UX improvements:

clearer version display with clickable badge and cleaner About layout.

Files touched (key):

src/meritscalc/qt_ui.py — ClickableLabel, import version, and extensive About tab layout/styling changes.
src/meritscalc/main.py — adjusted imports to package-qualified form.
src/meritscalc/version.py — version bump to 1.0.6.

Notes:

No breaking changes expected.
Typical installs (pip install . / python -m meritscalc) should continue to work, however if you run from source, ensure PYTHONPATH/entrypoint is set so package imports resolve.
