short URL generator - should use new domain or get domain from browser

[lexingxie]

with influenceflower.cmlab.dev now active ...

the permanent link url says https://influencemap.cmlab.dev/submit/?id=AAAAAAEs-HwX
and we'd want it to say influenceflower in the URL

is shorterner.py the right place to change?

The base URL for the main webpage has been updated.
The requests coming from arXiv are still using the old domain. So, we need to keep the old URL as well for compatibility.
