Label blank account option "(None)" when no company default is set

The item account dropdowns showed "(Default … account)" on the blank
option even when the company hadn't configured a default — implying a
fallback that didn't exist. Now the blank option reads "(None)" unless a
matching company default is configured, in which case it keeps the
"(Default …)" label (the dropdown pre-selects the real account anyway).
"Has default" flags are computed in the shared dropdown-population helpers
so every render path (Create/Edit GET and invalid-POST) gets them.
