Miscellaneous Fixes (#20989)

* Include DB in safe mode config

Copy DB when going into safe mode to avoid creating a new one if a user has configured a separate location

* Fix documentation for example log module

* Set minimum duration for recording segments

Due to the inpoint logic, some recordings would get clipped on the end of the segment with a non-zero duration but not enough duration to include a frame. 100 ms is a safe value for any video that is 10fps or higher to have a frame

* Add docs to explain object assignment for classification

* Add warning for Intel GPU stats bug

Add warning with explanation on GPU stats page when all Intel GPU values are 0

* Update docs with creation instructions

* reset loading state when moving through events in tracking details

* disable pip on preview players

* Improve HLS handling for startPosition

The startPosition was incorrectly calculated assuming continuous recordings, when it needs to consider only some segments exist. This extracts that logic to a utility so all can use it.
