feat: report on the way with + and confirm arrival in the steward view [MET-A-015] - #293

Description

Second of two PRs for #263. The steward sets their status from the steward view during an active scenario:

• Every station under "Påvirkede stationer" shows how many have arrived out of how many are needed (e.g. 0 / 1) and a + button. Pressing + sends a position report and shows the steward as on the way to that station.
• On the way, a yellow card says "DU ER PÅ VEJ", a dark card shows the station, the status and the coverage, and a slide "GODKEND ANKOMST" confirms arrival.
• Arrived, a green card says "DU ER ANKOMMET".
• Picked the wrong station? Pressing + on another station switches to it.
• With no status, the control says so and points to +.
• The chosen station is the steward's own station: it turns red on the map and "Opgaver på ..." shows its tasks (Sub-issue of MET-A-010: The steward's own assignment stands out #158).
• A refused report is shown in Danish. While the app shows the saved offline copy, + is hidden, the slide is locked, the steward is told why and nothing is sent.

Choices:

• • sits in "Påvirkede stationer", as in the sketch shown to the stakeholders.
• Arrival is confirmed with a slide, not a tap, as agreed at the sprint review, so it is not sent by mistake.
• Coverage counts only come from the server, so the steward sees the same as the control room.
• When the steward logs in again, the current status is fetched, so they see the status they had.
• Words, colours and the symbol come from stewardStatus and the status colours in Theme.tsx (feat: show steward status as word, symbol and colour [MET-A-015] #287). The status card is a .tsx component (criterion 6).
• Only additions to ScenarioOverview and StewardView. The existing station picker for position reports is left as it is.

Context

#263, sub-issue of MET-A-015 (#15). Stacked on #291, which is stacked on #287.

How was it verified

• npm run test:unit and all Jest tests pass, including new tests for the status card, + in the station list, the chosen station as the own station, and the steward view going from no status to on the way to arrived, a refused report and the offline copy. typecheck, lint and format:check pass.
• Manually in Expo Go on the phone against the local server with a seeded scenario, logged in as steward:
  • "Ingen status" with + and coverage on each station
  • + gives "DU ER PÅ VEJ" with the station card and the slide, and the station turns red with its tasks
  • + on another station switches to it
  • Sliding all the way gives "DU ER ANKOMMET", and a short slide springs back
  • Logging out and in again shows the same status and station
  • Offline: "gemt kopi" is shown, + is hidden and the status cannot change
• Not checked on the A52/A55 emulator or at the largest font size.

Noticed, not fixed

• After arriving, the count under "Påvirkede stationer" and on the station card still shows 0 / 1. The count comes from the server, which does not know about arrivals yet, so the phone shows the same as the control room. It updates once the agreed event contract (ARRIVED) and the server change are in.
• Check out and "Fortryd" (cancel on the way) come in a follow-up PR after the agreed contract change.
• The steward view now has two ways to pick a station: the station picker for position reports (MET-A-013) and + for status (MET-A-015). Since + also sends a position report, the old picker could be removed later, once the integration team agrees.
• Task done (TASK_DONE) is not offered yet, since the sketches only cover on the way and arrived.
