Fix a list of found bugs

[Tiam-Abderezai]

• departure time sometimes shows bugs in journeys column (related: Add delay and remarks functionality)
• bottom of journeys list is hidden behind the bottom navigation; make it so it's above the bottom nav bar
• some bus lines don't fully connect to next stop in legs column (related: Add display switching between stops)
• RE lines show orange, not red; make them red
• map crashes when selected journeys from journeys screen is transferred over to maps screen
• make the dividing line between the maps box and journeys list in maps screen distinguishable and visible
• adjust the icon sizes to be easier on the eyes
