Fix toggle buttons covering Back button in ConfigScreen

[Copilot]

With 9 toggles and a fixed ypos increment, ConfigScreen overflows and buries the Back button. Refactors drawMenuButtons() to use the same scrollable-row pattern already established in ControlsScreen.

Changes

src/screen/configScreen.py

• Scrollable toggle list — drawMenuButtons() now calculates visibleRows from available vertical space (reserving 80px for the bottom strip), clamps scrollOffset, and renders only the visible slice. A "1–N of 9" indicator appears when content overflows.
• Fixed Back button — drawBackButton() replaced by drawBottomButtons(), which always renders at y - 45 regardless of toggle count, matching ControlsScreen.drawBottomButtons().
• Mouse wheel scroll — added handleScrollEvent(event) and wired pygame.MOUSEWHEEL in run().
• Visual consistency — rowHeight = 35, buttonHeight = 28, and bottom margin match ControlsScreen values exactly.
• scrollOffset lifecycle — initialized to 0 in __init__, reset to 0 on each run() entry.

# Before: fixed ypos, drawBackButton() called from inside drawMenuButtons()
ypos = 70
for label, attribute in toggleButtons:
    self.graphik.drawButton(xpos, ypos, width, height, ...)
    ypos += height + margin
self.drawBackButton()  # covered once ypos exceeds screen height

# After: scrollable slice + fixed bottom strip
visibleRows = int((y - startY - 80) / rowHeight)
self.scrollOffset = max(0, min(self.scrollOffset, maxOffset))
for i, (label, attribute) in enumerate(toggleButtons[self.scrollOffset:self.scrollOffset + visibleRows]):
    self.graphik.drawButton(xpos, startY + i * rowHeight, width, buttonHeight, ...)
# Back button drawn separately, always at y - 45
self.drawBottomButtons()

Pull request overview

Refactors ConfigScreen settings toggles to be scrollable so the Back button remains visible even when the toggle list overflows the screen.

Changes:

• Implemented a scrollable, row-based rendering for config toggles (with overflow indicator).
• Replaced the old back-button drawing logic with a fixed-position bottom button strip.
• Added mouse-wheel scrolling support and reset scroll state on screen entry.

visibleRows can become 0 (or negative) if the window height is small enough, which makes maxOffset and the slice math inconsistent (e.g., scroll offset can clamp beyond the last item and the range indicator can show something like "10-9 of 9", and no toggles render). Consider clamping visibleRows to at least 1 (or early-return with a message) before computing maxOffset/slicing.

Fixed in 2c90265 — visibleRows is now clamped to max(1, ...) so the slice math and range indicator remain valid even at very small window heights.
