💄 Redesign file explorer and isolate to shared component(s)

[aaronleopold]

• Abstracted the file explorer and associated components away from a library and more as a separate set of components
• Redesign the exploration aspect of the explorer
• Added virtualization with two different layouts:
  • Grid
  • Table
• Added skipped_files to the scanner output data type, which describes the number of files which already exist in the DB but have not been modified on disk since the last scan
• Added a smidge more concurrency
• Optimized a few heavier queries in the scan loop to only select required fields
• I removed the logic which loads and parses .stumpignore files 💥
• Fixed a few dead docs links
• I temporarily commented out the logic in the event handler which re-queries data on certain events. For now, only the very end when data is returned will re-querying happen. This will be work-shopped a bit more before experimental lands in nightly
