Fix button layout in delivery confirmation dialogs

[fwextensions]

• Fix #184.
• Add padding to the alert and make the buttons the same width.
• Make the alert z-index 1000 so it floats above the header as well. Currently, you can log out while the dialog is open.
• Add the same shadow as the header to the dialog, so there's a little separation with whatever's underneath.
• Update the text of the cancel ringdown and redirect confirmation dialogs.
• Fix the missing icon on the delivery canceled dialog.

The text could probably use some more wordsmithing, but seems like a step in the right direction. Another option for the button labels could be something like Yes, cancel delivery and No.

Also, Cancel incident might be a better label for that button. It's not like you're canceling the transport of the patient but keeping them in the ambulance. I assume it means the whole incident has been canceled for some reason.

Looks great! Thanks John

And you're good with the language tweaks?

These are definitely copy improvements - while we're at it, let's go with:

Redirect patient? You will need to choose a new hospital destination for the patient.

Choose new destination Keep destination

Cancel delivery? The hospital will be notified and the ringdown will be cleared.

Yes, cancel delivery No, don't cancel

Good question about canceling the 'incident' vs. 'delivery'. I'm not entirely clear on how this situation would occur, but I don't imagine we currently have the ability to tell dispatch to erase the incident, so for now let's stick with 'cancel delivery' until we have more clarity.

I've updated the text with those changes.
