This PR addresses #19586
I added a mutex to the upload version creation which will prevent the
push errors when two requests try to create these database entries. I'm
not sure if this should be the final solution for this problem.
I added a workaround to allow a reupload of missing blobs. Normally a
reupload is skipped because the database knows the blob is already
present. The workaround checks if the blob exists on the file system.
This should not be needed anymore with the above fix so I marked this
code to be removed with Gitea v1.20.

When starting a scroll while the mouse is over a mermaid diagram, the
scroll sometimes propagates to the iframe, preventing the parent page
from scrolling. Fix this by disabling scroll inside the iframe. This is
not a problem because those frames are never meant to scroll. Bug seems
to affect Firefox only.

This patch:
- Use `<button>` replace anchor link `<a>` in **_Delete/Restore
Branch_** button to avoid unexpected page jump before restore branch
actually done.
- Also replace right side buttons with `<button>` in branch list, let
some screen readers know they are buttons.
## Before
click restore branch -> restore triggered -> page refreshed, but branch
status not update -> manually refresh page
