fix: Handle SerenDB URLs without embedded UUID hostnames

When a SerenDB target URL does not have the expected
<database>.<branch>.<project>.serendb.com format with 36-char UUIDs,
the remote execution now gracefully falls back to using just the
connection string instead of erroring out.

This allows users to specify SerenDB targets with simpler hostnames
while still benefiting from cloud execution.
