Add basic repository lfs management (#7199)
This PR adds basic repository LFS management UI including the ability to find all possible pointers within the repository. Locks are not managed at present but would be addable through some simple additions.

* Add basic repository lfs management
* add auto-associate function
* Add functionality to find commits with this lfs file
* Add link to find commits on the lfs file view
* Adjust commit view to state the likely branch causing the commit
* Only read Oid from database
