Update copyright header end year to 2026

[mdickinson]

Bump the copyright end year from 2025 to 2026 across the source tree, and update EXPECTED_COPYRIGHT_END_YEAR in etstool.py to match.

This is the follow-up to #370: it brings the copyright headers up to the current year, which makes the non-blocking strict-style check pass again. The merge-blocking check continues to use EXPECTED_COPYRIGHT_END_YEAR (now 2026).

Every changed line is a pure 2025 → 2026 bump, preserving each file's original start year. The changes fall into these categories:

• Copyright headers at the top of 155 files (-2025 Enthought, Inc. → -2026 Enthought, Inc.) — at line 1 for .py files, and at line 2 for the two Sphinx apidoc templates docs/source/api/templates/module.rst_t and package.rst_t.
• setup.py: both the file header and the second copyright header inside VERSION_FILE_TEMPLATE (used to generate apptools/version.py).
• docs/source/conf.py: the file header plus the Sphinx copyright variable ('2008-2025, Enthought' → '2008-2026, Enthought'), which uses a different format from the standard header.
• etstool.py: the file header plus EXPECTED_COPYRIGHT_END_YEAR = 2026.

Verified locally that flake8 --select H102 reports no findings across the tracked source tree.
