Request to add API key for free SMS

Description

Sending SMS is very convenient but it is currently only possible to set up one number. To share notifications, would it be possible to add a key for a second Free number?

I would add that each API key should belong to a user account, which allows sending a message to Mr. or Ms.

This feature was already on my TODO list because we had discussed it when I did that integration

I’ve done a bit of work on it:

I’ll give it a try this weekend and put an image up for testing

Great, now each user can set their own Free API key.

I also added in the user list the option to message everyone

I’ll prepare an image if someone wants to test

The PR

and the image being built:

docker pull willde71/gladys-test:freemobile

Super, a big thank you @Will_71. I just need to manage to set up a second user :slightly_smiling_face:
