[FEATURE] Add "♥" (Избранное) button/icon

[ocolodeev]

Problem description

Problem
Accessing favorite destinations currently requires swiping up, which is less intuitive and takes extra steps. This slows down navigation and may be confusing for users who expect quicker access to frequently used locations.

Describe the solution you'd like

Solution
Add a ♥ (Избранное) button next to the existing “Current Location” and “Show Map” buttons. This will:

• Provide one-click access to saved destinations.
• Reduce reliance on gestures.
• Potentially make the swipe-up panel redundant or secondary.
