test(iteration-19): Add comprehensive unit tests and remove SSRF dead code

Coverage improvements:
- Applications service: 89.62% -> 100%
- Catalog service: 90.03% -> 100%
- Oncall service: 91.41% -> 95.84%
- Teams service: 92.62% -> 100%
- Integrations service: 83.2% -> 86.61%
- SSRF utils: 87.14% -> 100%
- Cleanup job processor: expanded test coverage

Code changes:
- Remove dead code in ssrf.ts (URL-encoded hostname checks unreachable
  because JavaScript URL constructor auto-decodes hostnames)

New test files:
- network-errors.test.ts
- report-export-pdf.test.ts

Total tests: 5701 (35 new tests added)
