Radial: add top-level 'Cursors to Line Ends' multi-cursor action

Multi-cursor on every selected line is a quintessential in-place action
(select lines, gesture, keep typing) — a natural fit for a top-level radial
slice. Wired to Kate's createMultiCursorsFromSelection via its visible text
'Add Cursors to Line Ends'.

findActionByName now falls back to a case-insensitive visible-text match
when the objectName lookup misses, so slices resolve across Kate versions
even when action ids differ. Dropped 'Select All' from the radial (reachable
via Ctrl+A and the palette). All 5 ctest suites green.
