buzzromainandClaude Opus 5 00894c169b fix(goals): treat moving a whole-account link as the fresh claim it is
Addresses review feedback on #3160.

The exclusivity check was bounded to `new_record? ||
will_save_change_to_allocated_amount?`. A persisted whole-account row whose
`account_id` or `goal_id` changes is neither, so moving one landed it on an
account nobody had checked — the same double-counting hole a restore opened,
through a different door.

The bound is widened rather than dropped. It exists because `Goal has_many
:goal_accounts, autosave: true` revalidates every loaded child on `goal.save`,
so an unguarded check makes a goal that merely holds a legacy overlap
impossible to rename. That reason still holds for every row along for the ride;
it does not hold for a row being moved. A test pins both faces.

bin/rails test: 6939 runs, 27916 assertions, 0 failures. RuboCop and Brakeman
clean. Confirmed load-bearing by narrowing the bound back and watching the move
test fail.
