Merge pull request 'fix: Keep ROCK tile after surface rock mining (Issue #48)' (#49) from fix/rock-tile-preserved into master

CHANGE_TILE ROCK→GRASS removed from the surface-rock harvest branch.
Empty ROCK tiles are now passable (no resource on them) but remain ROCK,
so the mine building can still be placed on harvested rock ground.

Fixes #48

 ### Fixed
+- **Debug-Panel überlagert Nisse-Info-Panel** (Issue #41): F3-Debug-Panel weicht dynamisch aus — wenn das Nisse-Info-Panel offen ist, erscheint das Debug-Panel unterhalb davon statt darüber
 - **Stockpile-Overlay Transparenz** (Issue #39): `updateStaticPanelOpacity()` verwendete `setAlpha()` statt `setFillStyle()` — dadurch wurde die Opacity quadratisch statt linear angewendet; bei 100 % blieb das Panel sichtbar transparent
 - **Action Bar Transparenz** (Issue #40): Action Bar ignorierte `uiOpacity` komplett — Hintergrund war hardcoded auf 0.92; wird jetzt korrekt mit `uiOpacity` erstellt und per `updateStaticPanelOpacity()` live aktualisiert
