Drop READ_MEDIA_IMAGES, bump to 1.2.35+151

Play's photo and video permissions policy refused version 150 over this, and
was right to. The policy allows the permission only where a system picker is
"technically insufficient to provide core app functionality", and the app's
real need is the opposite of that:

  * every operational photograph opens the camera directly — parcel shots at
    pickup, proof of delivery at the door, stop verification. None read the
    library, deliberately: a picture chosen from the gallery could have been
    taken anywhere at any time and would not be evidence that a parcel was
    collected or delivered;
  * the one gallery read in the whole app is a rider setting their profile
    photograph, once, at sign-up.

That is the textbook "one-time or infrequent" case the policy points at the
Android photo picker for. image_picker 1.1.2 already routes
ImageSource.gallery through that system picker on Android 13+ when the
permission is absent, so the profile picker keeps working and needs no
permission at all.

READ_EXTERNAL_STORAGE stays, still capped at maxSdkVersion 32, for devices
older than the photo picker.

Verified absent from the built bundle's merged manifest rather than only from
the source.
