- boring cleanup and little fixes:
- when you set the checker options in the edit subscription dialog, the queries now recalculate their file velocity better. previously, they would just set 'unknown' and recalc on the next run, but now they will actually recalculate if the query container is loaded into memory or otherwise put a status that says 'will calculate on next run'
- removed the 'should be namespaced' reason from the manage tags quick petition reasons. this is now all handled by siblings, tidying up storage tags manually is busywork
- when you click 'copy traceback' on an error popup, it also copies the software version, your platform, and if you are on a frozen build or running from source
- the logger now prints version number for every block, just before the timestamp
- cleaned up a variety of media viewer UI code while working on the scanbar, fixing some misc display bugs
- moved pixel hash storage responsibility from 'file metadata' to 'similar files' module
- the similar files system now searches pixel hashes when it is called to do any similar files search. they count as 'exact match' distance
- when a file gets a new pixel hash, it now sees if any other files have that same hash. if so, it now gets queued up again in the similar files search system, ensuring this match is not missed
- misc nomenclature cleanup--since we now have both 'pixel hashes' and 'phashes', phashes are now referred to as 'perceptual hashes' everywhere
- massively refactored the primary table join that drives potential duplicates search. it should work a bit faster now and it is much easier to work with
- I added pixel dupe and distance search to the standard search results version of the join and the 'system:everything' version, which has several optimisations
- silenced some shutdown handling in file maintenance that was being printed to log as an error
- fixed some 'broken object load' error handling to print the timestamp of the specific bad object, not whatever timestamp was requested. this error handling now also prints the full dump name and version to the log, and version to the exported filename. I was working with a user who had broken subs this week, and lacking this full info made things just a little trickier to put back together
- fixed some drag and drop handling where it was possible to drop thumbnails on a certain location of a page of pages that held an empty page of pages but it would not create a new child media page to hold them
- misc serverside db code cleanup
- fixed python 3.10 type bugs in window coordinate saving and Qt image generation from buffer (issue #1027)
