Fix #405: push_back() on script-created vector has no effect if vector_conversion is in effect (#663)
* Fix #405: push_back() on script-created vector has no effect with vector_conversion

When both vector_type<T> and vector_conversion<T> are registered, the
dispatch scoring treats all parameter mismatches equally. This causes
the C++ push_back (for the converted type) to be selected over the
built-in one when both have the same number of type differences. The
converted function operates on a temporary copy of the vector, silently
discarding the mutation. The fix deprioritizes overloads that require
type conversion on the first parameter (the object/receiver), ensuring
functions matching the receiver type exactly are always tried first.

* Address review: remove issue references from comments, add round-trip conversion tests

Requested by @lefticus in PR #663 review.
