Omnisearch in front

[ptitFicus]

The idea is to have a search bar present in Izanami topbar.

Search should display a result box as you type, that indicates search results.

Search should search among :

• Features
• Projects
• Tags
• Tenants
• Api Keys
• Webhooks
• Users

When clicking on a result entity that does not have a dedicated page, for instance a feature, we should display a page when resulting entoty is visible (for feature it should be project page) and either highlight feature or filter feature table to keep only resulting feature visible.
