_auth_properties not being cleared on process_authority

[takeshibaconsuzuki]

🐛 Description

After setting input's multiplayer authority, we are supposed to call process_authority(). process_authority does not clear _input_property_config._auth_properties. This means subsequent calls to get_properties_owned_by() do not update _auth_properties and we return the old incorrect value. This prevents inputs from being recorded correctly, causing _can_simulate to always return false, and thus client nodes are never simulated / never send input to the server.

Steps to reproduce

• Have avatar + input + rollback sync in scene tree
• Wait a few ticks after scene starts (to allow _ready's deferred process_settings to be called)
• Set input multiplayer authority and call process authority

Expected behavior

• Client should simulate
• Server should get input and simulate

Observed behavior

• Client does not simulate
• Server does not get input

Versions

• Godot version: 4.4.1
• netfox version: 1.30.1
