📄 Description

Describe your changes

Follow-up to #6762. Removes the remaining special-cases that kept lazy connections from applying uniformly, and lets the embedded reverse proxy interoperate with Rosenpass-enabled peers.

Run the lazy connection manager for Rosenpass-enabled peers instead of disabling it outright. Such connections simply never idle on their own, since Rosenpass rekey traffic keeps them active.
Treat forward-target peers as normal lazy connections instead of forcing them always-active; they wake on demand like any other peer.
Run Rosenpass in permissive mode on the embedded proxy so it can connect to Rosenpass-enabled peers (post-quantum) and fall back to plain WireGuard for peers without it. Without this a Rosenpass peer cannot reach the proxy at all (PSK mismatch). Toggle with NB_PROXY_ROSENPASS (default on).

Summary by CodeRabbit

New Features
- Added embedded-client options to enable Rosenpass post-quantum key exchange and configure permissive behavior.
- Added environment-variable controls for Rosenpass and embedded-client log level settings.
- Rosenpass is enabled by default for embedded clients and can be overridden through configuration.
Improvements
- Improved lazy peer connection handling so peer activity follows configured lazy policies more consistently.
- Enhanced startup and configuration logging, including Rosenpass settings and clearer invalid log-level warnings.
