Add exit node enforcement section (Auto Apply + disableNetworks)

[SunsetDrifter]

What

Adds an Enforcing the Exit Node on Managed Devices section to the exit nodes use-case page, answering the question the page currently leaves open: Auto Apply "is not a lock" — so how do you lock it?

• The recipe: exit node with Auto Apply enabled + the disableNetworks client policy (MDM key on Windows/macOS, netbird service install --disable-networks on Linux). Enforcement happens in the daemon, so GUI and CLI are equally locked.
• Names the two likely mistakes: reaching for disableUpdateSettings (locks configuration, not network selection), and deploying the lock after users have already deselected the exit node (a saved deselection keeps winning over Auto Apply; includes the recovery).
• States the boundary honestly: netbird down is not gated and there is no always-on mode — pair with OS-level controls and access-policy design.
• The Auto Apply concept section now forward-links to the new section, and the MDM Integration page gets a reciprocal note under disableNetworks.

Why

Recurring customer/POC question ("can users turn the exit node off?"). The pieces exist across the exit nodes and MDM pages, but the connective recipe and its ordering caveat are written nowhere. Behavior verified against client v0.77.0 on Linux (service flag) and macOS (managed preferences), including the GUI.

Summary by CodeRabbit

• Documentation
  • Added guidance for enforcing exit-node usage on managed devices.
  • Documented configuration, rollout order, verification, recovery from previous selections, and enforcement limitations.
  • Clarified that disabling network selection with an auto-applied exit node pins devices to that node and prevents deselection.

Poem

A rabbit reads the policy bright,
And pins the exit node just right.
Auto Apply leads the way,
Locks the switch for every day.
Deploy, verify, and hop away!
