Add safety cap to ComicVine issue pagination

[dotMavriQ]

Summary

• Caps ComicVine volume issue fetching at 10 pages (1000 issues) to prevent request timeouts on very large series

Test plan

• Import a large comic series (100+ issues) and verify it completes without timeout
• Verify the 1000 issue cap doesn't truncate normal-sized series
