Merge #7341: fix: repair dash-chainstate dist sources

a42b90b fix: repair dash-chainstate dist sources (pasta)

Pull request description:

  ## Issue being fixed or feature implemented

  The `make distdir` and `dash-chainstate` packaging/build paths referenced stale source paths after recent address index and governance refactors. This caused CI packaging/build jobs using `--enable-experimental-util-chainstate` to fail.

  ## What was done?

  - Updated `dash_chainstate_SOURCES` to use `index/addressindex.cpp` and include its standalone helper/source dependencies.
  - Replaced removed governance source entries with the current governance source files used by the tree.
  - Updated `bitcoin-chainstate.cpp` to match the current `LoadChainstate` setup flow after the governance/superblock manager refactor.

  ## How Has This Been Tested?

  - `./configure --enable-experimental-util-chainstate`
  - `make -C src -j4 dash-chainstate`
  - `git diff --check`
  - `rm -rf dashcore-distcheck-test && mkdir dashcore-distcheck-test && (cd src && make top_distdir=../dashcore-distcheck-test distdir=../dashcore-distcheck-test/src am__remove_distdir=: am__skip_length_check=: am__skip_mode_fix=: distdir)`

  ## Breaking Changes

  None.
