Codex runner on Windows launches PowerShell as login-shell and decodes
stdout/stderr without UTF-8, garbling Cyrillic output. The other 51 ps1
scripts already set `[Console]::OutputEncoding = UTF8`; bring these 7
in line and add `InputEncoding = UTF8` for symmetry.
Touched: epf-init, erf-init, form-add, form-remove, help-add,
template-add, template-remove. Versions bumped in both ps1 and py
headers to keep the pair in sync.
