Add Turkish Translation (tr.php)

Hello team, I have created the Turkish language file for MailWatch. Best regards.

*Added Turkish language support. Translated by Alper Peri.

Thanks for working on this translation.

I do not know Turkish myself, so this is only an AI-assisted review based on a comparison with mailscanner/languages/en.php, and the comments below should definitely be taken with some caution. That said, I did not notice syntax issues, missing keys, broken placeholders, or major mistranslations that would introduce clearly wrong meaning.

A few items still look worth adjusting before merge:

• messages05: English is Messages, but Turkish is Mesaj. This should probably be Mesajlar.
• spamwl04, spambl04, mcpwl04, mcpbl04: current wording is understandable, but reads more like list names than status labels. It may be worth aligning them more closely with the “Allowlisted / Blocklisted” meaning of the English source.
• title59: Karantina Serbest Bırakma is understandable, but feels a bit literal. Something like Karantinadan Serbest Bırakma or Karantinadan Çıkarma may sound more natural.
• unknownvirusscanner03: the English source includes (see FAQ), which seems to be omitted in Turkish.
• message115: the English source mentions that GeoIP files are updated on the first Tuesday of each month; that detail seems to be missing in Turkish.

Also, beyond tr.php, it looks like Turkish should probably be added in the other translation files in the // 99 - General section near the end of those files, so the language list stays consistent. And mailscanner/conf.php.example should likely be updated as well, since it currently lists supported languages as de, en, es-419, fr, it, ja, nl, pt_br and the USER_SELECTABLE_LANG example does not include tr.

So overall: this looks solid and useful, but I would suggest fixing messages05, considering the wording tweaks above, and updating the remaining language lists/config examples so Turkish is wired in consistently.
