Post installation

EDIT: OK, I'll try to recast this question somewhat based on my ongoing research.

I would appreciate advice and instruction from anyone who uses Hostinger or is familiar with it.

So far, I have not found a normal person's guide to the above, so — thinking ahead — I asked the support chat bot how to update a Drupal site and it told me that I would need to manually replace all of the files in the file manager and run update.php.

I'm creating tutorial for admin pages. It should not be accessible by guest users. How can I achieve that? I couldn't find permission pane. 

I'm creating the page based on newly created contents type and block type, but it is ok to use other types if only default basic page or article page can achieve that.

Drupal 10, olivero subthemes

thanks

I have a block that displays for anonymous users that I cannot find in any configuration or structure settings: blocks or menus.  The link does not work and the webform it points to does not exist.  Any suggests on how to delete this would be appreciated.

When bulk uploading images (Media Bulk Upload) is there a way to auto-generate separate nodes for each image?

I have a list of events on different days of the week, I have them sorted Monday to Sunday, is there a way to sort them so so when monday has passed it shows the next day (tuesday) at the top with Monday going to the bottom of the list

Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday

but when Monday has passed (if no events in Monday) sort order is

Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday, Monday 

and same for other days.

hope this makes sense.
 

I want to store user-uploaded files on a CDN (probably bunny.net). I don't want to store them on my domain (mydomain.com). Is there a method or a module that facilitates this?

I am assuming that if this is possible, I'd put a CDN URL in the File (Field) Path setting:

I am aware of the CDN module (https://www.drupal.org/project/cdn), but this appears not to interact with uploaded files, just the serving of files.
