## Summary
- Refactors SSRF protection from a request-level adapter to
connection-level agents, validating resolved IPs in `createConnection` +
socket `lookup` events
- Sets both `httpAgent` and `httpsAgent` so validation applies
regardless of protocol switches during redirects
- Caps `maxRedirects` to 10 as defense in depth
## Test plan
- [x] All 59 existing + new unit tests pass (agent util, isPrivateIp,
service)
- [x] No linter errors
- [ ] Verify webhook delivery still works with URLs that redirect
- [ ] Verify image upload from external URLs still works (relies on
redirect following)

> [!NOTE]
> **Medium Risk**
> Changes core outbound HTTP security behavior and redirect handling,
which could impact webhook/image-fetch flows and connection semantics
despite improved SSRF coverage.
>
> **Overview**
> Refactors outbound SSRF protection from a custom axios `adapter` to
connection-level `httpAgent`/`httpsAgent` created by new
`createSsrfSafeAgent`, which blocks private IP literals up front and
validates DNS-resolved IPs via the socket `lookup` event.
>
> When safe mode is enabled, `SecureHttpClientService.getHttpClient` now
always installs both agents and enforces a capped `maxRedirects`
(default `5`), and the old `getSecureAxiosAdapter`
implementation/tests/types are removed. `isPrivateIp` is
tightened/expanded to treat `0.0.0.0/8` as private and avoid
misclassifying bare IPv4 decimals as IPv6.
