setup: recreate an incomplete .venv instead of activating it

Browse Source 
A failed venv creation (e.g. the Debian/Ubuntu python3-venv package
missing) left the .venv directory behind; the next run saw it, skipped
creation and failed to source/activate a venv without activate/pip.
setup.sh now validates bin/activate, bin/python and bin/pip, removes an
incomplete directory and creates it again; a creation failure removes the
partial directory and names the venv package.  setup.bat does the same
with Scripts\activate.bat/python.exe/pip.exe and !errorlevel!.

READMEs (prerequisites + scripts table), CHANGELOG (folded into the
unreleased 3.38.1) and AGENTS updated.

Tests: tests/test_setup_scripts.py (5: the shell/bat source pins and
bash -n).  1088 Python + 1075 frontend.

### Prerequisites
- **Python 3.9+** with `pip`, and **Git** — the app runs on 3.9+, but the **SCP81 TLS-PSK listener needs Python 3.13+** (`ssl`'s PSK callbacks).
- **Python venv support** — `setup.sh` creates `.venv`; if that fails with `ensurepip is not available` (Debian/Ubuntu ship the venv module separately), install it (`sudo apt install python3-venv`) and run `./setup.sh` again. An incomplete `.venv` left by the failed run is removed automatically.
- **Smart card reader** (PC/SC or serial/FTDI) — PC/SC is preferable (`pcsc-lite` + `ccid` on Linux). `pyscard` has no Linux wheels, so it builds from source: install the PC/SC header package too (`libpcsclite-dev` on Debian/Ubuntu, `pcsc-lite-devel` on Fedora; on Arch `pcsclite` includes them).
- **Windows** — use **Python 3.13 (strongly recommended)**: `pyscard` has precompiled wheels up to 3.13 and the SCP81 TLS-PSK listener needs 3.13+. On 3.14 `pyscard` and some pysim dependency wheels are not available and build from source (needs MSVC C++ Build Tools). 3.9–3.12 run the app but not the SCP81 PSK listener. The SMPP bridge (`smpp.twisted3`) is intentionally skipped on Windows.
