Subject: refactor(pinentry): remove bundled `m_pinentry` module

* Delete all source and resource files related to the internal pinentry
  functionality.
* Stop building the pinentry module in the main build system.
* Simplify structure and reduce maintenance overhead by relying on external
  pinentry utilities.
* May affect passphrase input and related UI flows; verify integration points.
