fix: Fixed error handling

The v2 API requires a different JSON payload structure than what was being sent.
Both DeleteApp and DeleteAppInstance needed to wrap their parameters properly.

SDK Changes:
- Update DeleteAppInput to use {region, app: {key}} structure
- Update DeleteAppInstanceInput to use {region, appinst: {key}} structure
- Fix DeleteApp method to populate new payload structure
- Fix DeleteAppInstance method to populate new payload structure

CLI Changes:
- Add delete command with -f flag for config file specification
- Support --dry-run to preview deletions
- Support --auto-approve to skip confirmation
- Implement v1 and v2 API support following same pattern as apply
- Add deletion planner to discover resources matching config
- Add resource manager to execute deletions (instances first, then app)

Test Changes:
- Update example_test.go to use EdgeConnectConfig_v1.yaml
- All tests passing including comprehensive delete test coverage

Verified working with manual API testing against live endpoint.
