G-Codes from subfolder fixes

The bot will warn you if you have broken/non-working options in the config.

New features

• You can run any arbitrary macro/g-code after a photo is taken. This is useful, if you want for example to park the head before taking the picture, and resume immediately after the photo is taken. See the new command in the interacting with klipper section and the new parameter in the config.
• The status message does not autoupdate when a m117 command is run. You can enable this behaviour in the config, see the telegram ui section.

Fixes

• Added CI, many thanks to @KapJI
• Fixed issues when g_code was located in a subfolder, thanks to @xyzroe
• Small fixes to sensor display in status messages
• Delay after the picture is taken is now equal to the delay before the picture is taken.
• FPS calculation for some edge case scenarios for timelapses is now fixed
• JWT-Token refresh is now implemented
• Preview is added for uploaded files
