feat(server): run credentials verification on the connection import endpoint

[hassan254-prog]

Describe the problem and your solution

• run credentials verification and connection validation on the connection import endpoint

---

It also adds structured log context lifecycle handling around success and failure paths and expands API error typing to expose new error codes when credential tests or validation fail.

Possible Issues

• Credential test failures are treated as 400; confirm alignment with existing API semantics for invalid credentials.
• Custom validation failure deletes only on creation; ensure expected behavior for override operations.
