fix: improve test cleanup to prevent secret accumulation (#132)

* fix: improve test cleanup to prevent secret accumulation

- Fix defer placement in ephemeral tests to ensure cleanup runs even if tests fail
- Add comprehensive cleanup patterns for all test secret naming conventions
- Enhance cleanup utility with better pattern matching and time-based cleanup
- Add helper functions for aggressive cleanup of test secrets

Fixes #131

Co-authored-by: Luis M. Gallardo D. <lgallard@users.noreply.github.com>

* fix: address remaining code review findings

- Fix resource leak risk with proper time validation in helpers.go
- Fix test reliability by moving defer after successful deployment
- Fix performance issue by consolidating API calls and adding pagination
- Add bounds checking to prevent clock skew issues

* fix: address critical test cleanup and reliability issues

- Add pagination support to helpers.go ListSecrets to prevent missing secrets
- Standardize cleanup time windows to 6 hours consistently across all cleanup functions
- Improve race condition handling by separating init/apply in ephemeral tests
- Add time bounds validation to cleanup/main.go pattern matching
