Manager GUI refactoring | Image preview with data overlay + capture counting streamlined

With this change the image preview part of the Manager tab has been reworked with the goal to provide substantially more informations about the current capture session:

The new version contains the following changes:

• details about the currently running capture below the image frame
• a text overlay showing details about the displayed captured frame and the capture history (overlay can be enabled/disabled from the floating bar)
• navigate through the captured frames
• option to delete the currently shown frame
• introduce a horizontal progress bar for capture progress of the current frame
• make the round progress bars less space consuming
• add a pure text version for information about the progress state of current sequence, current job and total
