Other Nav Modes Camera and Non Navigation UI Improvements

[hactar]

This PR tries to bring iOS closer to Android by porting parts of the commits:

• 0d3c088 (Android route overview / isNavigating overlay gating)
• 0ee36b8 (adds NavigationActivity camera modes tied to Android - Create default MapViewCamera for other navigation modes #165)

This PR should therefore also address #196

Concrete changes:

• Camera not tilted in non navigation mode
• buttons hidden in non navigation mode
• demo button for choosing destination moved outside the .navigation grid, cause its not a navigation button (this is different to the android set up)
• adjustments to the demo relative path of where to find the ferrostar lib (no longer requires the root folder to be called ferrostar)
• function and test adjustments as iOS was adding the current road label even if it was nil, which android didn't

Video of the demo app before changes (notice the camera tilt at the beginning and the nav buttons visible on the right side) :

Video of the demo app after changes (no tilt, nav buttons only visible during nav):

Please note that things go wrong if you try to start a second navigation, she search field no longer disappears. But this happens before these changes too, so I didn't address it to not further inflate this PR.

Nice! I'll give this a test but here are a few quick comments from reading the code.

I feel like we lost something with this test since the view no longer renders :)

[hactar]

with "view no longer renders" you mean the Text view?

So for me, the tests were not passing on my computer. When I looked at the expected screenshots, they did not contain the yellow text box - yet the new snapshot did, like this:

Looking at the android logic, the road name is not displayed when empty there, so i used that logic in iOS instead of the "Unknown" label (https://github.com/hactar/ferrostar/blob/ios-sync-165-and-overlay/android/composeui/src/main/java/com/stadiamaps/ferrostar/composeui/config/NavigationViewComponentBuilder.kt#L63) - but this was just an assumption, if we need something else here I'll need more info :).

Huh weird...

Yeah, it's test code so I don't have an issue with it differing between platforms. I've added it back so these render and we can get a sanity check on layout changes. Lemme know if this still causes issues for you developing locally.
