Fixed a small typo and rendering of the rest of the content when database connection would fail in Admin Panel (SettingsController class)

[Goatform]

Before

• Realm Settings page on admin panel had a small < typo and would render the rest of the content that was supposed to fail (not work) anyway.
• Pvp Rewards page on admin panel had no db checks at all and in case of some db related error would output massive error log (at least on local env.) so I added db connection check for it as well.
• Added a db error log handling for Tools page as well but we only perform if some change was attempted (Only upon POST request) instead of doing it immediately

UPDATE: Put all of the stuff within try / catch handler to handle every exception properly instead of doing additional DB checks to see if DB connection is proper etc (also previously you had no global error checks and this will fix it)

NOTE: Ideally I'd implement global exception handler for this (admin / dev / local only) instead of handling this stuff for every logic separately.

After

• Removed a small typo < at the end of echo string
• Used wp_die (PHP die equivalent) to stop rendering the rest of parts because they will always fail for the most part.
• Exposed error text to WP's __ translation function in case it gets added eventually (won't cause any issues if it doesn't exist and provided text in code would be used as default instead)

Here's how it looks after adding those changes:

There's mistake that I've done using ACoreServices::I()->getAccountRepo() , gonna fix that later on when I have time. Just putting it out here in case someone was about to comment on it.

Now, this one should be resolved with 17da5ff
