feat(server): xmp sidecar metadata (#2466)

* initial commit for XMP sidecar support

* Added support for 'missing' metadata files to include those without sidecar files, now detects sidecar files in the filesystem for media already ingested but the sidecar was created afterwards

* didn't mean to commit default log level during testing

* new sidecar logic for video metadata as well

* Added xml mimetype for sidecars only

* don't need capture group for this regex

* wrong default value reverted

* simplified the move here - keep it in the same try catch since the outcome is to move the media back anyway

* simplified setter logic

* simplified logic per suggestions

* sidecar is now its own queue with a discover and sync, updated UI for the new job queueing

* queue a sidecar job for every asset based on discovery or sync, though the logic is almost identical aside from linking the sidecar

* now queue sidecar jobs for each assset, though logic is mostly the same between discovery and sync

* simplified logic of filename extraction and asset instantiation

* not sure how that got deleted..

* updated code per suggestions and comments in the PR

* stat was not being used, removed the variable set

* better type checking, using in-scope variables for exif getter instead of passing in every time

* removed commented out test

* ran and resolved all lints, formats, checks, and tests

* resolved suggested change in PR

* made getExifProperty more dynamic with multiple possible args for fallbacks, fixed typo, used generic in function  for better type checking

* better error handling and moving files back to positions on move or save failure

* regenerated api

* format fixes

* Added XMP documentation

* documentation typo

* Merged in main

* missed merge conflict

* more changes due to a merge

* Resolving conflicts

* added icon for sidecar jobs
