decompiler: fix stale scroll frame on same-function jump

DecompView.goto derived its scroll with _scroll_cursor_into_view() -> a plain
scroll_to, which updates scroll_offset but doesn't repaint at the new offset
(Textual only repaints on a rounded scroll change, and there's no layout pass
since the pane isn't reloaded). So a same-function xref jump landed the cursor
correctly but painted the old scroll until the next cursor move nudged a repaint.

Route goto's scroll (derived or explicit) through _apply_scroll, which re-applies
after the next refresh with layout=True -- the same pattern show() uses. The
cross-function path already worked because reloading + clearing the loading cover
forces a fresh paint. Document the gotcha in TEXTUAL_NOTES.

full suite 64/64.
