Show an indicator corresponding to the room full capacity rate

[fcamblor]

Floxx app should be able to send us realtime rooms' full capacity rate so that we can display it into voxxrin.

Impacts :

• @fcamblor Provide a dedicated endpoint for Floxx App with a dedicated token to access it
• @fcamblor This endpoint will fill a dedicated (public) firestore collection /events/{eventId}/roomsStats having following structure :

{
    "1709": { // 1709 is a room ID, DevoxxFR's Amphi Bleu here...
        "lastUpdatedOn": "2024-04-17T07:02:15Z",
        "fullCapacityRate": 1.0
    },
    "1705": {
        "lastUpdatedOn": "2024-04-18T08:28:00Z",
        "fullCapacityRate": 0.93
    }
...
}

• @fcamblor On schedule page, we should display an indicator for upcoming rooms having a talk in it :
  • If we didn't get any fullCapacityRate raised by red coats (we don't have any entry for target room OR lastUpdatedOn for this room is before previous talk's end time minus 10% of its duration OR lastUpdatedOn for this room is after target talk's end time minus 10% of its duration), we should display a small "?" indicator
  • If fullCapacityRate is < 0.6, we should display a green indicator stating there are still plenty of available seats
  • If fullCapacityRate is >= 0.6 and < 0.8, we should display a yellow indicator stating the room is becoming crowded
  • If fullCapacityRate is >= 0.8 and < 0.99, we should display a red indicator stating that only few seats are left
  • If fullCapacityRate is >= 0.99, we should display a black indicator that the room is full
• @robinlopez to provide UI for this indicator
• @fcamblor to check if an event crawling is not going to reset room stats (we've got a strange behaviour on wed 3rd, where every room capacities were resetted)

@robinlopez If you could think about an indicator above schedule cards to show this colored information, it would be nice (given that it's only a temporary information useful only for next talks, I would not add this INSIDE the card, but maybe ON TOP of it) :

Here is the UI for room capacity indicators (these are only displayed for upcoming time slots)

@fcamblor Design adjustment OK

Great idea to have a dedicated icon for full rooms ! 😍

closing as I'll consider this as merged into develop
