[73986] Prevent browser title truncation at 70 chars

https://community.openproject.org/wp/73986

The meta-tags gem truncates the page title to 70 characters by default,
which caused the browser title bar to show incomplete page titles.

Add initializer that disables that limit so the full title is always
displayed.
