Add `Event Property` to sidebar menu clicks based on their associated panel

Description

We added the navigation events in #402711 (closed) / !115877 (merged). These events need the Event Property setting based on the panel they belong to.

The available panels can be found here: (Permalink)

Note: This is a permalink, check master for latest panels. Admin for example.

Proposal

Map the panels to an appropriate event nav_panel_[panel_name]. e.g:

panel name	event property
project	nav_panel_project
user_profile	nav_panel_user_profile

We should do this in a generic enough way that when new panels are added we can easily/automatically set the Event Property.
