Shane Ringrose 207c0c9544 Fix copyright years and deduplicate terminal names
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", …
