fix(edit-wo): pass panel='tenant' to Page::getUrl()

Without an explicit panel, WorkOrderDashboard::getUrl() resolves the
route name against Filament's current-or-default panel, which in some
Livewire lifecycles or from ambiguous contexts is 'central' — where
the page isn't registered. Symptom: the produced URL ended up empty
or malformed, and clicking the button hit our friendly redirect
claiming WO #0 doesn't exist.

Also removes the temporary /__wo-diag/{id} route added for diagnosis.
