chore: migrate ansys-tools-path -> ansys-tools-common (#4307)

* chore: migrate ansys-tools-path -> ansys-tools-common

Update dependency, imports, docs, links, and tests to use ansys-tools-common
(ansys.tools.common.path) instead of ansys-tools-path. Add _HAS_ATC feature
flag and provide a backward-compatible _HAS_ATP alias. Adjust CLI/help text,
sphinx intersphinx mapping, workflow comment, and numerous test patches to
reflect the new package name.

* chore: adding changelog file 4307.maintenance.md [dependabot-skip]

* Update src/ansys/mapdl/core/report.py
