fix(outbounds): persist optional blocks and fix stale edit reopen

- derive XMUX toggle from saved xmux on load, seed defaults on enable,
  and drop xmux when disabled (#4654)
- save the JSON tab straight from parsed text so sockopt, finalmask (TCP
  masks), mux, and reverse excludes round-trip instead of being dropped
  by the form-store bounce
- remove the redundant Host/Path fields from HTTP obfuscation that fought
  the request.headers editor over the same form path
- rebuild the outbounds table columns on row content change (rows, not
  rows.length) so a re-opened edited outbound shows fresh values
- add adapter round-trip regression tests

Closes #4654
