BUILD-10792 Remove copyright years from license header templates (#41)

* BUILD-10792 Remove copyright years from license header templates

Drop ${license.years} from all bundled headers; align SSALv1 and
SonarSource templates with dateless wording and legal link.

* Address PR review: MIT (C) consistency; SSALv1 wrap without trailing space

- Align MIT copyright line with AL2/GNU LGPL/SSALv1 (C) convention.
- Break SSALv1 sentence at word boundary so stamped headers have no
  trailing whitespace (sonar-review-alpha).

* SSALv1: strip trailing space after PURPOSE. in header template
