Remove redundant CLEM workflow components

[tieneupin]

Now that the CLEM workflow has been running for a substantial amount of time, we've identified that certain components introduced as part of the initial setup are unnecessary. This PR removes those excess components from the repository.

• Removed LIF, TIFF, image stack and metadata tables from the Murfey database
• Removed functions and logic blocks related to their registration
• Refactored the CLEMImageSeries table into a more general purpose ImagingSite table, which can be used for multiple workflows
