After full review of current MAIL_ENCRYPTION usage in laravel and
smyfony mailer, this updates the options in BookStack to be simplified
and specific in usage:
- Removed mail.mailers.smtp.encryption option since it did not actually
affect anything in the current state of dependancies.
- Updated MAIL_ENCRYPTION so values of tls OR ssl will force-enable tls
via 'scheme' option with laravel passes to the SMTP transfport, which
Smyfony uses as an indicator to force TLS.
When MAIL_ENCRYPTION is not used, STARTTLS will still be attempted by
symfony mailer.
Updated .env files to refer to BookStack docs (which was updated for
this) and to reflect correct default port.

WKHTMLtoPDF provides limited control for external fetching
so that will now be disabled by default unless
ALLOW_UNTRUSTED_SERVER_FETCHING=true is specifically set.
This new option will also control DOMPDF fetching.
- Added testing to cover.
- Linked logging into Laravel's monolog logging system and made log
channel configurable.
- Updated env var names to be specific to login access.
- Added extra locations as to where failed logins would be captured.
