Addresses CodeRabbit review on #3226, "Skip hidden corner destinations"
and "Keep merged destinations inside the selected area": with column D
hidden, Ctrl+. on B2:D3 made D2 active; with B1:C1 merged and column C
selected, it made B1 active, outside the selection. A corner in a hidden
row or column, or one whose merged cell starts outside the selected
area, is now passed over like a locked corner on a protected sheet.
Test: next_corner_skips_hidden_corners_and_stays_inside_the_selected_area.

Addresses CodeRabbit review on #3226:
- "Check the next corner against protected-sheet selection rules": on a
sheet protected without Select Locked Cells, Ctrl+. could make a locked
corner active. It now goes on to the next corner it may select.
- "Keep the active cell at a merged cell's anchor": a corner inside a
merged cell made that cell active instead of the merge's top-left
cell. The corner now lands on the top-left cell, and corners in the
same merged cell are one stop.
Selection::next_corner_by takes where each corner leads (or None to skip
it); next_corner keeps its plain behaviour.
Tests: next_corner_skips_corners_the_sheet_protection_does_not_let_you_select,
next_corner_stops_once_on_a_merged_corner_at_its_top_left_cell.

Excel's Next Corner of Selection (Ctrl+., Control+. on a Mac) moves the
active cell clockwise to the next corner of the selected area (top-left,
top-right, bottom-right, bottom-left) and keeps the area selected; the
new active cell is also the anchor, so Shift+arrows then move the
opposite corner. GridCraft had no such command.
New command selection.nextCorner (Selection::next_corner) bound to
Ctrl+. on every platform. A one-row or one-column area goes end to end;
a single cell stays where it is.
