Release v11.6 - Bugfixes and major backend improvement preparations

[Wotuu]

General changes:

• Map header is too busy in weekly route #2590 Reduced the amount of users that you can see when route syncing to 1. To view more users, press the three dots to see a full list. This will help with the header being too crowded on popular routes.

Route changes:

• Pull descriptions have a max length of 255 #2582 Pull descriptions can now have up to 500 characters (up from 255).

Bugfixes:

• Editing a route's settings replaces the title incorrectly #2591 Editing a route's name no longer replaces it with the new title incorrectly in the header.
• Vertical align elements in pull row in the sidebar #2545 Various elements in the pull sidebar now properly align vertically.
• Show across all routes in team should be a checkbox #2584 "Show across all teams" for map icons is now a checkbox as intended.
• Editing a map icon doubly-applies the Facade conversion #2484 Editing an object twice in a row while in combined floor mode (MDT map style) no longer applies translations twice, leading to an incorrect placement of the object.
