Original Pull Request: https://github.com/netbirdio/netbird/pull/6675

State: open
Merged: No

Describe your changes

Adds CLI parity for reverse-proxy Access Control Rules when creating peer-initiated expose services with netbird expose.

The new flags are:

--allow-ip
--block-ip
--allow-cidr
--block-cidr
--allow-country
--block-country

Single IP flags are normalized to /32 or /128 CIDRs before being sent to management, matching the existing reverse-proxy access restriction model.

Implementation details:

Threads access restrictions through the daemon expose request, management expose request, and reverse-proxy peer service creation flow.
Reuses the existing AccessRestrictions backend model and validation.
Keeps auth flag behavior unchanged: L4/TLS still reject password/PIN/user-group auth, while access restrictions apply to both HTTP and L4 services.
Preserves crowdsec_mode when peer-created expose services receive the shared AccessRestrictions proto.
Adds focused tests for CLI normalization, request conversion, proto mapping, service validation, and service construction.
