Two issues raised in PR review:
1. Copyright year: new files carried "2006" (the project's founding year).
Updated to "2006-2026" to reflect the actual authorship period.
2. Duplicate terminal names: EPLAN parts can have multiple connection
templates sharing the same connectionDesignation (e.g. a drive where
both wire entries of terminal "1" are labelled "1"). QET requires
unique terminal names for wiring and terminal-diagram generation.
Resolution order in EdzElementBuilder::build():
- Unique designation → used as-is.
- Duplicated designation with distinct sanitised description →
"designation_description" (e.g. "1_L_P").
- Otherwise → numeric suffix: "1", "1_2", "1_3", …

Replaces the QProcess->7z shim with the public-domain LZMA SDK (23.01) 7-Zip
reader, vendored under sources/import/edz/lzma/ (decode-only subset). New
edzsevenzip.cpp wraps SzArEx_Open/SzArEx_Extract and writes entries via Qt, so
EdzArchive no longer needs an external 7-Zip at runtime. Enables the C language
in CMake for the vendored sources.
Verified: the bundled decoder extracts all three ifm sample .edz and the
generated elements still match the Python oracle exactly (byte-correct decode),
with no 7z on the path.
