fix: increase Play Store upload timeout and add retries

The httplib2 default timeout (60s) was too short for AAB uploads, causing
transient TimeoutError failures in CI. Switch to an AuthorizedHttp with
a 300s timeout and pass num_retries=3 to all .execute() calls.

Also add google-auth-httplib2 and httplib2 to the Nix devshell Python
packages so the imports resolve at runtime.
