decomp: Home/End move along the line instead of scrolling to top/bottom

The pseudocode view still had the old mapping (home -> goto_top, end ->
goto_bottom), so <End> jumped you to the bottom of the function instead of the
end of the line. Bring it in line with the listing view:

  home        start of line          ctrl+home   top of the function
  shift+home  first non-blank        ctrl+end/G  bottom of the function
  end         end of line

shift+home skips the C indentation — the pseudocode analogue of the listing's
skip-the-address-gutter.

Verified live and locked in view_toggle (5 checks): <end> stays on the line with
the scroll unchanged, <home> hits column 0, <shift+home> lands on the indent
width, and ctrl+home/ctrl+end still reach top/bottom. Full suite 179/2-flake.
