feat(mobile): Add people list to exit bottom sheet (#6717)

* feat(mobile): Define constants as 'const'

* feat(mobile): Add people list to asset bottom sheet

Add a list of people per asset in the exif bottom sheet, like on the
web.

Currently the list of people is loaded by making a request each time to
the server. This is the MVP approach.
In the future, the people information can be synced like we're doing
with the assets.
