Email row: fix crash from leftover menu-wrap wiring after button removal

I removed the .email-menu-wrap markup from email rows earlier but
left the JS that queries it and calls .addEventListener on the
result. Since the query returns null, every _createEmailItem call
threw and the row never made it into the list — most visibly:
clicking a sender name to filter by them didn't appear to work,
because the row wiring (including the sender click handler) was
ripped out mid-construction.

- Drop the unconditional menuWrap.addEventListener('click', ...)
  block — there's no menu to open.
- Drop the early-return guard on touchstart that referenced the
  removed wrap.
- The two remaining .email-menu-wrap queries are already guarded
  with 'if (menuWrap)' so they safely no-op.
