fix: Tab back from a decomp jump returns to the listing cleanly

Regression from the decomp-jump feature: _open_decomp_entry clears
_decomp_return, so Tab out of a jumped-to pseudocode view hit the fallback that
just re-showed the (stale) listing widget WITHOUT reopening it and left
_cur.view == "decomp". Two visible symptoms:
  * the listing showed the wrong/old function, and
  * a subsequent rename ran _reload_active_code -> _open_entry(cur), which saw
    view == "decomp" and bounced back into the decompiler; the rename also
    appeared not to propagate (you were looking at stale pseudocode).

Fixes:
  * Tab from decomp with no F5 snapshot now opens the listing at the current
    pseudocode line's address (a real listing view, _cur.view = "listing"),
    so the correct function shows.
  * _reload_active_code forces _cur.view = "listing" when refreshing the
    listing, keeping the entry consistent with what's on screen.

Verified: F5 -> follow ref in decomp -> Tab -> listing shows the TARGET function;
renaming a label there stays in the listing and reflects the new name
(RELABELED: and 'jnz RELABELED'). view_toggle/decomp_nav/decomp_follow_self/
follow_xrefs/xref_labels/rename/rename_history/disasm_nav/search/mouse/
listing_view/continuous_view/func_banners 70/0.
