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.

First piece of native EPLAN Data Portal (.edz) import. A .edz is a 7-Zip
archive; QET previously had no archive handling. EdzArchive unpacks one to a
temporary directory and locates the contained part.xml.
The extraction backend is isolated behind extractWithSevenZipCli() so it can be
replaced with a bundled decompressor later without touching callers; this M0
step shells out to a 7-Zip CLI via QProcess. Verified on three ifm sample
parts (KG6000, MFH200, R1D200 — all 7z), plus the corrupt/missing-file paths.
