Added test `test_process_url_validate_redirect_hook_blocks_unsafe_url` to cover the scenario where `validate_redirect` hook aborts the `httpx.AsyncClient` request, which resolves the 0% code coverage diff hit detected by the CI check `codecov/patch`.

Combined duplicated `event_hooks` keyword arguments into a single dictionary parameter with both `validate_redirect` and `verify_redirect` in `app/api/url_upload.py`. This fixes a `SyntaxError: keyword argument repeated: event_hooks` and ensures that all redirect validations run.

Fixed a `SyntaxError: keyword argument repeated` in `app/api/url_upload.py` where `event_hooks` was being passed twice as a keyword argument to `httpx.AsyncClient`. Combined both SSRF redirect validation hooks into a single list `event_hooks={"response": [validate_redirect, verify_redirect]}`. This restores critical SSRF protections via redirect validation and fixes the application crash.

🚨 Severity: HIGH
💡 Vulnerability: The `/process-url` endpoint used `httpx.AsyncClient` with `follow_redirects=True`. While the initial user-provided URL was validated against SSRF protections (blocking private/internal IPs), the client implicitly followed subsequent HTTP redirects without validating their target locations. This allowed an attacker to bypass the initial check by supplying a valid URL that redirected to an internal IP or cloud metadata endpoint.
🎯 Impact: An attacker could potentially access internal network services or cloud metadata endpoints.
🔧 Fix: Implemented an `event_hooks` listener (`validate_redirect`) on the `httpx.AsyncClient` that intercepts responses, extracts the `Location` header, resolves the absolute target URL, and applies the same `validate_url_safety` check before allowing the redirect to be followed.
✅ Verification: Ran `pytest tests/test_url_upload.py`, formatting checks via `ruff format` and linting via `ruff check`.

- Resolve merge conflicts with main (PR #834 also fixed S3 SSRF)
- Add isinstance(endpoint_url, str) type check before urlparse to prevent TypeError on non-string values
- Reject endpoint_url with empty/missing hostname after parsing (malformed URLs like 'https://')
- Keep scheme validation (http/https only) and private IP blocking via is_private_ip()
- Add logger.warning for SSRF block events
- Add regression tests: non-string endpoint_url and empty hostname cases
- Update sentinel.md with consolidated SSRF entry

Adds missing unit tests for `_test_imap_connection` and `_test_s3_connection` to cover the new `is_private_ip()` SSRF blocking logic and satisfy Codecov checks.

Adds validation using `is_private_ip()` for user-provided hosts in `_test_imap_connection` and `_test_s3_connection` to prevent Server-Side Request Forgery vulnerabilities.
