Itinerary improvements

[graue]

While a basic version of the detailed itinerary is done, there's a lot left to improve:

(some of these may be worth splitting into separate issues!)

Tier 1: before considering the feature done

• [x] #148
• [ ] #396
• [x] #129
• [x] #189

Tier 2: nice-to-haves

• [x] #218
• [x] play with showing more transit stops
  • more-vert icon to represent default-hidden ones
  • default: show 1 or 2 additional stops after boarding stop and/or before alighting stop
  • button (looks like a link? blue text?) to expand and reveal all stops
• [x] #149
• [x] #170
• [x] #173
