Mute: Nodes

[ford-jones]

Resolves #7943

Introduces mechanisms to mute message notifications received from certain nodes.
When a message is received from a muted node, the device's buzzer (if present) should not be activated. Drawing of any alert UI notification to the device's screen should also be blocked.

The exception to this is bell alerts (when activated), which should still sound the buzzer and display a notification.

It should be noted that this behaviour is distinctly different to ignoring a node - an action which blocks the message entirely. Muted messages can still be viewed in the messages menu of the device or client application, they are just delivered discreetly - similar to muting a channel.

• Buzzer always sounds when no nodes are muted
• OLED popup always displays when no nodes are muted
• When a specific node is muted, messages received from that node don't invoke the buzzer or a popup

@garthvh Here's the one for nodes, should we revisit this in future.
Will leave it in draft for now.

@garthvh the is_muted flag has now been added to NodeInfo, let me know if this checks out 👍
