Commit Message

Fix `Initialize.gates_to_uncompute` for integer inputs  (#16492)

* fix: Initialize.gates_to_uncompute preserves num_qubits for integer-bitmap inputs

Initialize.gates_to_uncompute() was rebuilding the uncomputation circuit
via Isometry(self.params, 0, 0). For amplitude-vector inputs this works
correctly, but for integer-bitmap inputs (e.g. Initialize(1, num_qubits=2))
self.params only contains the stored integer, so Isometry sees a length-1
vector and returns a 0-qubit circuit.

The fix delegates to self._stateprep.definition.inverse(), which is the
same StatePreparation path already used for the forward direction and
correctly handles all documented input forms including integer-bitmap.

Fixes #16413

* address review: move test to test_initializer.py and simplify release note

* address review: simplify test and fix release note link

Per @Cryoris's review on PR #16492:
- Removed the redundant amplitude-vector comparison in the regression
  test; that input form is already covered elsewhere.
- Removed unnecessary local import of Statevector, which is already
  imported at module level.
- Fixed the release note to use the proper issue-link RST syntax.

* fix: remove extra blank line (black formatting)
